ST has been serving customers in the automotive market for over 30 years and provides them with a range of products and solutions covering most applications in a typical vehicle. As the market has evolved, so has ST’s offering, a key part of which is automotive microcontrollers (MCUs).

ST pioneered embedded non-volatile memory (eNVM) with ST10 and then introduced automotive microcontrollers with its SPC5 range based on PowerPC architecture, shipping more than one billion MCUs in automotive. Cost-effective automotive controllers from the STM8 family complemented this offer.

ST’s Stellar Family

ST’s latest generation of automotive microcontrollers is the Stellar family, which is the industry’s first Arm®-based portfolio that spans the entire automotive MCU spectrum, from low-end to high-end solutions. These advanced microcontrollers reduce complexity, ensure safety and security, and deliver optimal performance and efficiency of next-gen vehicle architectures and features. Customers can benefit from shorter development times and focus on bringing innovation and differentiation for their software-defined vehicles (SDVs) in this highly competitive market. For these reasons Stellar products are gaining momentum, particularly among our customers in Asia and Europe.

Stellar is the industry’s first family of emerging technologies after eFlash, representing the most mature and smallest memory cell automotive grade solution on the market. The Stellar family is optimized for electrification, including X-in-1 vehicle motion control computing, new vehicle architectures, zonal and domains, and safety MCUs for safety-critical subsystems, such as ADAS.

It fully supports automotive transformation by integrating multiple functions safely into a single device and allowing the continuous integration of new features in vehicles. This is made possible with key technologies, including a right choice of core technology, virtualization, Ethernet support and ground-breaking memory technology embedded in the automotive MCUs–a game changer for customers faces challenges with application memory sizing.

Stellar MCUs are based on Arm® Cortex®-R52+ technology. This high-performance processor delivers real-time virtualization support for time-critical secure and safety systems. It can run multiple applications simultaneously with freedom from interference. And thanks to fully programmable auxiliary cores it is possible to accelerate specific functions, such as routing, low power management, digital filtering while offloading the main cores.

“As the driver experience continues to evolve in the age of AI and software-defined vehicles, advancing automotive functional safety, flexibility and real-time performance capabilities is essential,” said Dipti Vachani, senior vice president and general manager, Automotive Line of Business, Arm. “Built on Arm, the Stellar microcontroller family taps into the Arm compute platform’s advanced safety and real-time features, as well as the broad Arm software ecosystem. This enables car manufacturers to comply with strict safety regulations while implementing innovative features that keep them at the forefront of the automotive industry.”

Stellar MCUs enable the introduction of ethernet capabilities in vehicles and is the first ST MCU embedding an Ethernet switch. Thanks to Ethernet, data exchange is more efficient, and flexible, supporting the needed gigabit throughput, with a higher level of security. By supporting various in-vehicle communication topologies, such as Ethernet ring, automotive MCUs fulfill the promise of halving the length of the cross-car wiring cables and manufacturing costs.

Phase Change Memory is set to redefine what is possible in vehicle software

Stellar MCUs, with the embedded Phase Change Memory (PCM) technology and its flexibility, transform the process of Over-the-Air (OTA) updates. In the automotive industry, OTA updates are crucial for adding new features and safety or security patches without physical intervention. However, this flexibility often requires careful consideration of future memory needs, which can lead to increased costs and complex planning.

ST’s PCM innovation is no ordinary memory. Not only is it the industry’s smallest memory cell for automotive MCU, but it is pioneering a transformative breakthrough in automotive and set to redefine what is possible in vehicle software. Thanks to ST’s innovative PCM technology, memory capabilities are reaching a new level of sophistication. This is not just about memory performance. It is a forward-thinking solution that brings adaptability and lasting value to the automotive landscape enabling the final developers to continuously improve and upgrade functions.

As vehicles become increasingly software-defined, the ability to introduce new features and enhancements is essential. PCM’s groundbreaking technology will support the shift toward more adaptable, future-focused vehicles, giving automakers new ways to refine experiences as vehicles continue to advance.

Additionally, PCM delivers the ability to support uninterrupted OTA updates. PCM securely stores updates without impacting the vehicle’s current operations. Thanks to concurrent read and write capabilities, the new software download does not interfere with the application code already running on the MCU, ensuring continuous performance during the update process.

Stellar P, designed for the integration of multiple functions, and Stellar G, for the realization of Software-Defined Vehicles (SDV) zonal controllers, are two series leveraging ST’s internally developed eNVM. They are built on 28nm FD-SOI technology, allowing them to achieve maximum frequency with lower power consumption and enhanced radiation immunity. Stellar is the first 28nm product certified for functional safety and will enter production by the end of this year.

The Stellar family also enables the X-in-1 growing trend toward more affordable electromobility, with the decisive switch from fossil to electrically powered vehicles. X-in-1 powertrain solutions combine multiple components into a single ECU, allowing manufacturers to create efficient, compact, and cost-effective performing vehicles.

Stellar offers scalable X-in-1 implementation, accommodating a growing number of ECUs from low to high integration levels. This solution supports increasingly complex X-in-1 systems by providing enhanced availability of cores, analog components, and I/O capabilities.

“As a global leader in lithium-ion batteries, Sunwoda provides stable and reliable electronic system solutions for automotive suppliers worldwide. Our new collaboration with STMicroelectronics focuses on developing solutions using ST’s advanced Stellar microcontrollers and proprietary production processes, which primarily include battery management systems, and VDC/Zonal and body control functions. Together, we aim to provide intelligent solutions that enhance the next generation of energy vehicles in China and globally,” said Wang Mingwang, founder, Sunwoda.

STM32 microcontrollers to enter automotive

As part of the expanded roadmap for automotive MCUs, ST will introduce its market-leading general-purpose STM32 microcontroller platform to the automotive sector. The STM32 platform is well recognized for its cost optimization, simplicity, and reliability. Augmented with automotive grade quality and safety, STM32A will achieve up to ASIL B standards. This platform will be designed to handle edge actuation, from the simplest functions to more sophisticated single tasks, all at optimized costs. It will be particularly well-suited for applications like motor control in vehicle systems, including windows, mirrors, and roofs.

Best of industrial and automotive worlds: towards converged future

Over time, the convergence of the industrial and automotive hardware and software platforms will combine the best of both worlds. Automotive brings strong security expertise and industrial is built on strong Internet of Things and artificial intelligence solutions. The converged future will share hardware technologies, cores, and a common ecosystem of tools and software support. Such convergence will enable customers to seamlessly transition between solutions, offering simplification and full scalability to innovate faster.

Edge AI technology is one example where we see what is being adopted now in industrial applications benefiting automotive in the future. Neural accelerator technology and the associated tools that enable developers to easily implement AI in their applications, whatever their level of data science expertise, will enhance automotive systems in the future. ST has spent approximately 10 years investing in the development of microcontrollers, smart sensors, and AI software tools to meet the needs of our customers and harness the power of edge AI.

While AI adoption in automotive—beyond autonomous driving—is still in its initial stages, there are emerging trends of promising use cases for system optimization, energy efficiency, and problem-solving. For example, virtual sensors can measure rotor temperatures, and predictive maintenance can ensure vehicle reliability. As the number of sensors in vehicles heavily increases, AI will play a key role in virtualizing many of them, further enhancing automotive performance. Security is another area where we see the convergence of industrial and automotive bringing significant benefits.

This future will be based on the most advanced and more efficient 18nm process technologies. ST’s advanced technology portfolio for automotive MCUs spans from 40 to 28 to 18nm, selected to optimize product performance and cost.

The benefits of the IDM model for our customers

As an integrated device manufacturer (IDM), ST develops fundamental semiconductor process technologies, creates core intellectual property (IP), designs products using these technologies and IP, and manufactures, tests and packages them using owned facilities or through partnerships. This brings several benefits for our customers:

• Processes designed and refined to meet the applications needs of our customers in various markets.
• IP blocks optimized for specific functions and systems, owned by ST.
• Manufacturing processes are optimized for key performance and yield through the tight teamwork between process, product, and operational teams.
• Control of manufacturing capacity and creation of flexible, reliable supply chains.

This is particularly important for our automotive customers.

An example of these benefits is the combination of FD-SOI and PCM technologies that ST has developed for its Stellar microcontrollers. ST was one of the key innovators in both technologies, working with partners to bring them to market. ST’s ability to master the technology and tailor it to automotive applications has resulted in products with unique benefits. ST’s implementation of PCM technology has allowed the creation of the smallest physical memory cell in the industry delivering 2x the memory density of alternatives.

Thanks to the high-energy efficiency, high reliability, and radiation immunity of this memory technology, ICs designed in FD-SOI with embedded PCM meet the most stringent requirements of automotive applications. ST’s PCM technology achieves automotive requirements for AEC-Q100 Grade 0 with an operating temperature up to +165°C. The patented technology supports high-temperature data retention, including during solder reflow, so firmware can be uploaded before soldering.

Ecosystem plays a key role for transformation

An extensive partner ecosystem from developer tools to specific libraries for safety, security, and data exchange and distribution, augmenting ST’s portfolio capabilities further complements this leading technology. This will also provide the necessary simplification, aiding our customers in their transformation journey towards software-defined vehicles.

“STMicroelectronics and Green Hills Software are working closely together to deliver innovative integrated hardware and software solutions that address the growing challenges automotive OEMs and Tier 1s face in next generation vehicle zonal architectures.” said Dan O’Dowd, Founder and CEO at Green Hills Software. “Green Hills production-proven safety-certified RTOS and tools, coupled with ST’s Stellar SR6’s unique communication IP, deliver advanced fault tolerant zonal networking that enables significant per-vehicle cost savings while reducing time-to-market.”

“With MICROSAR Classic, we enable our customers with safe and secure basic software for ECUs for a wide range of use cases. Thanks to many years of close cooperation with ST, the corresponding support for the new Stellar MCUs is already available,” says Jochen Rein, Director of the Product Line Embedded Software and Systems at Vector. “By integrating Stellar’s advanced hardware with Vector’s robust software, customers get the highest level of safety and reliability for both ADAS applications and to successfully manage the transition to Software-Defined Vehicles.”

“iSOFT is a leading developer of automotive operating systems in China and the premium partner of AUTOSAR for China’s infrastructure software. Since the introduction of its collaboration with ST in 2016, iSOFT has become ST MCAL agent in China. This includes multiple microcontrollers such as SPC58/SPC56/STM8A, and the companies will also engage in a deeper strategic cooperation on the newly introduced Stellar family that will support EasyXMen Open Source Operating System in the future.” Luo Tong, Vice President, iSOFT

As the Trump administration proposes the introduction of “reciprocal tariffs”—taxing imports at the same rate foreign governments impose on U.S. goods—the global electronics and semiconductor industry is bracing for ripple effects that could redefine supply chains, trade routes, and strategic investments. With India emerging as a serious contender in global electronics manufacturing, these policy shifts could present both opportunities and challenges for the country’s growing semiconductor ambitions.

Global Supply Chains in Flux

The electronics and semiconductor sectors are among the most intricately connected global industries. From chip design in the U.S. and Taiwan, to wafer fabrication in South Korea and China, to final assembly in India and Vietnam—every component in a finished product typically crosses multiple borders. A tariff war threatens to disrupt these finely tuned global supply chains.

This risk was underscored recently when President Donald Trump announced a staggering 104% tariff on Chinese electric vehicles, shaking global markets. Reacting to the tariff hike, Tata-owned Jaguar Land Rover halted its shipments to the U.S. for a month in response to a separate 25% import tariff, citing sudden cost pressures and logistical uncertainty. These developments signal a volatile phase for companies relying heavily on cross-border operations.

For India, which imports up to 88% of its semiconductor requirements, disruptions in sourcing from East Asian hubs could cause short-term volatility in the availability and pricing of key components. Additionally, higher tariffs could push up input costs for Indian manufacturers exporting to the U.S., making pricing less competitive.

A Tailwind for ‘Make in India’?

However, there’s a silver lining. As geopolitical tensions rise and multinationals seek “China Plus One” strategies, India is increasingly viewed as a viable alternative. The Indian government’s push under the Production Linked Incentive (PLI) scheme, coupled with new semiconductor fabrication plans and robust demand for electronics, places the country in a favorable position to absorb diverted investments.

This shift is already underway. Apple and Samsung are reportedly accelerating plans to shift manufacturing to India, partly to hedge against Trump’s rising tariffs on Chinese goods. Apple, for instance, has already begun iPhone production at Foxconn’s Tamil Nadu facility, with plans to ramp up output in 2025. These strategic realignments bolster India’s role in the global value chain.

If reciprocal tariffs deter trade between the U.S. and China, Indian manufacturers may gain a competitive edge—particularly in segments like PCB assembly, mobile manufacturing, and back-end chip packaging. This could catalyze India’s ambition to become a $300 billion electronics manufacturing hub by 2026.

Impact on Competitiveness

Over 80% of the U.S. semiconductor industry’s production is destined for international markets, making it highly dependent on global exports. Imposing higher tariffs may weaken its global competitiveness, particularly if retaliatory measures by other countries kick in. On the flip side, Chinese manufacturers could double down on building self-reliant supply chains, while Indian firms may find new export opportunities if trade patterns realign.

Yet, uncertainties remain. India’s electronics industry still depends significantly on imports of chips and sub-components. Tariff-induced disruptions could lead to cost escalations, affecting price-sensitive consumer markets both in India and abroad.

Export Pressures & Strategic Realignment

With India expanding its export capabilities in smartphones, consumer electronics, and electric vehicle components, increased trade barriers may force a rethinking of pricing strategies. Electronics brands exporting to the U.S. could face squeezed margins or may need to reroute operations to avoid tariffs.

To stay competitive, global electronics firms may explore shifting part of their production from China to tariff-neutral zones such as India, Mexico, or Southeast Asia. This trend, already underway post-COVID-19, may accelerate under tariff-driven pressure.

Policy Implications for India

India must walk a fine line. While these global shifts could open up new export windows, there’s also a risk of becoming collateral damage in a broader trade conflict. To safeguard domestic manufacturers and leverage emerging opportunities, the Indian government should consider:

• Negotiating strategic trade agreements with the U.S., EU, and ASEAN nations.
• Providing greater ease-of-doing-business incentives for relocating manufacturers.
• Accelerating semiconductor ecosystem development to reduce import dependencies.
• Offer temporary tariff shelters or rebates for affected MSMEs in electronics exports.

Conclusion: A Defining Moment

The Trump administration’s proposed tariffs may well be a turning point for the global semiconductor and electronics industry. For India, this could serve as both a test and an opportunity—to deepen its electronics manufacturing base, attract foreign investments, and reposition itself as a trusted global partner in a rapidly changing trade environment. Strategic foresight, nimble policy responses, and continued innovation will be key to navigating the challenges ahead.

We’re excited to announce Virtualizer Native Execution for Arm-based machines. This groundbreaking virtual prototyping technology will transform how software is developed for edge devices and applications — particularly in the automotive, HPC, IoT, and mobile industries.

Virtualizer Native Execution enables a paradigm shift in edge-focused software development via improved:

• Simulation performance. Virtualizer Native Execution significantly boosts the performance of virtual prototypes — speeding up software development, debugging, and testing.
• Development productivity. Virtualizer Native Execution leverages cloud-native approaches to enhance productivity, reduce toolchain silos, and make modern development workflows more accessible for embedded software engineers.

Extending the industry-leading virtual prototyping solution to the Arm ecosystem

The market-leading virtual prototyping solution with the largest library of models and IP,Virtualizer enables developers to work with virtual prototypes of target hardware instead of physical setups that are location-dependent and difficult to scale.

Virtualizer Native Execution extends the complete Virtualizer tool suite to the Arm ecosystem, allowing virtual prototypes to be built, executed, and tested directly on Arm-based machines. And because it can be leveraged across development and computing environments — on-premises, in the cloud, and at the edge — it eliminates toolchain and workflow silos and helps increase development flexibility and agility.

Virtualizer Native Execution significantly boosts development speed and efficiency via:

• Native execution. Instead of simulating the target hardware’s CPU on an Instruction Set Simulator (ISS), Virtualizer Native Execution enables virtual prototypes to be executed directly on the host CPU. This significantly reduces boot times (from 20 minutes to tens of seconds for a typical Android boot).
• Scalability. Modern Arm host machines offer more than 96 cores, and Virtualizer Native Execution can directly map each core of the virtual system-on-chip (SoC) to a physical core to greatly accelerate prototype performance.

Supporting the increased adoption and development of Arm-based systems

Arm-based CPUs have long dominated the mobile market, and in recent years they’ve been increasingly used for automotive, IoT, consumer, and other edge-based applications. Those in the cloud and HPC markets have also embraced Arm CPUs and IP, which provide an alternative to traditional x86-based solutions and deliver exceptional performance, power, and cost benefits.

This widespread adoption is leading to greater alignment and uniformity of the CPUs and toolsets being used across on-premises, cloud, and edge environments. Often referred to as Instruction Set Architecture (ISA) parity, this uniformity provides new opportunities to streamline development efficiency and flexibility.

Virtualizer Native Execution supports the increased adoption and development of Arm-based solutions and takes advantage of ISA parity to supercharge software development and edge innovation.

Combining virtual prototyping with hardware-assisted verification (HAV)

Virtualizer Native Execution also supports hybrid emulation, which combines the unique strengths of virtual prototyping and hardware-assisted verification (HAV). Tightly integrated with Synopsys HAV solutions, Virtualizer Native Execution supports hybrid setups where the CPU subsystem is virtualized and the rest of the device under test (DUT) is emulated. And because it eliminates ISS overhead and runs natively on the host CPU, Virtualizer Native Execution is able to keep up with the fastest emulation systems (including the new ZeBu-200).The speed and scalability of Virtualizer Native Execution also enable new emulation use cases, like application-driven performance and power validation.

Taking embedded software development to the cloud

Developing embedded software for edge devices has long been a fragmented process involving complicated lab setups, delicate test boards and cables, and disparate toolsets. Not only has this hindered efficiency and scalability, but it has prevented the adoption of modern, agile development processes.

With Virtualizer Native Execution, developers can:

• Build and scale CI/CD pipelines in the cloud.
• Take advantage of higher performance and throughput as well as faster boot times.
• Replicate and align virtual prototypes across development and operating environments — on-premises, in the cloud, and at the edge.

Virtualizer Native Execution for Arm marks a significant leap forward in edge-focused software development. With better performance and scalability, native execution on Arm-based machines, and cloud-to-edge parity, developers can supercharge their virtual prototyping workflows.

High-performance AI data centers are reshaping semiconductor design and investment trajectories like no technology we’ve seen. As recently as 2022, spending on AI infrastructure was in the vicinity of $15 billion. This year, expenditures could easily top $60 billion. Yes, that sucking sound you hear is the oxygen being pulled from every investment plan and breathed into data centers.

We are clearly operating in an era of unprecedented artificial intelligence capital outlays – notwithstanding the potential impact of newcomers like DeepSeek. But while high-performance computing processors from Nvidia, AMD, and others are busy stealing the limelight, the high-bandwidth memory that stores training and inference models is having its day too – with 2024 DRAM revenue setting a record of nearly $116 billion.

Data center servers are driving a continuous increase in CPU core count, which requires more memory capacity to make higher-bandwidth data available to each processor core. But the laws of physics are quickly catching up. A CPU signal can only go so fast and far. That’s where memory interface devices such as register-clock drivers and data buffers come into play. By allowing the clock, command, address, and data signals to be re-driven with much-improved signal integrity, these interfaces enable the entire memory subsystem to scale in speed and capacity.

Today, RCD empowers registered DIMMs (RDIMMs) to operate up to 8 Giga Transfers per Second (GT/s). Most data center servers use RDIMMs, although some HPC systems need even greater memory subsystem performance.

Memory Interfaces Further Accelerate DRAM and Processor Performance

Notable for the vital role it plays in data center server systems, DRAM architecture hasn’t actually changed dramatically over the past three decades. Increases in density, speed, and power efficiency can be attributed largely to deep-submicron semiconductor scaling, while new 2.5D and 3D stacked DRAM packaging allows for higher-capacity DIMM modules.

As explained above, advances in memory interface technology – beginning with synchronous DRAM and carrying across multiple generations of double data rate DRAM – have played an outsized role in helping the interface keep pace with processor speeds.

Multi-rank DIMMs (MRDIMMs) are an innovative technology designed for AI and HPC data center applications. Made possible through a partnership between Renesas, Intel, and memory suppliers, MRDIMMs allow the memory subsystem to scale to much higher bandwidths compared to RDIMMs on corresponding server systems. Specifically, MRDIMMs double the data transfer speeds of the host interface by enabling two ranks of memory to fetch data simultaneously, which yields a six percent to 33 percent improvement in memory bandwidth.

Renesas DRAM Interfaces Help Close the Processor-to-Memory Performance Gap

Late last year, Renesas released the first complete memory interface chipset solution for second-generation DDR5 MRDIMMs. With an operating speed of 12.8GT/s, this represented a huge improvement in terms of how fast we can drive the interface compared to the 8.0GT/s maximum for a standard DIMM.

How did we get there? Through a combination of highly orchestrated component technologies. Since its inception at Integrated Device Technology, before it was acquired by Renesas, we’ve been on a mission to solve one problem confounding memory performance: signal integrity.

As the speed gap between DRAM and the CPU began to grow, the physical loading of the DRAM was becoming a problem for system architects. We saw an opportunity to address the challenge through our analog and mixed-signal design competency. The first in line was an RCD we used to intercept and redrive the clock signal and command address between the DRAM and processor. Subsequently, we developed a line of fully buffered DIMMs, which encapsulated all types of signals on the system memory interface, including clocks, command addresses, and data.

Fast forward, and our newest DDR5 memory interfaces include second-generation RCDs and data buffers for MRDIMMs in addition to a power management IC (PMIC), making us the only company to offer a complete chipset solution for the next-generation of RDIMMs and MRDIMMs. In addition, Renesas has made a significant contribution in helping power efficiency by evangelizing a concept called “voltage regulation on DIMM.” Voltage regulation circuitry now sits directly on the DIMM, as opposed to the motherboard, which allows for a more efficient, distributed power model. This is done using PMICs that locally generate and regulate all the necessary voltages needed by various DIMM components.

Leveraging the Electronics Design Ecosystem for the Future

Renesas has amassed a vast base of in-house expertise by collaborating with a large design ecosystem of leading CPU and memory providers, hyperscale data center customers, and standards bodies like JEDEC. That gives us the freedom to remove the bottlenecks that stand in the way of our ability to continue increasing DIMM speeds and capacity by determining how many DRAM components can be populated and how fast they can run.

It also opens opportunities to leverage technologies developed for AI data centers and redirect them to emerging use cases. That’s true for the higher processing and memory bandwidth requirements influencing designs at the edge of industrial network controls, where data must be captured and turned into actionable insights. And, it applies to the surging data volumes required by automotive safety and autonomous driving applications, which are quickly turning our vehicles into servers on wheels.

The moon — an environment full of extremes that can push even the most advanced technologies to their limits. Abrasive dust blocks sensitive sensors, temperatures as low as -150°C challenge conventional electronics, and the complete absence of GPS makes precise navigation nearly impossible. Such conditions demand innovative solutions tailored to the unique requirements of this extraordinary environment.

Bosch brings its technological expertise to a visionary project funded by NASA’s Tipping Point program with $5.8 million. In collaboration with Astrobotic, WiBotic, the University of Washington, and NASA’s Glenn Research Center, the project unites contributions from leading innovators. CubeRover(TM), developed by Astrobotic, is the mission’s lightweight and modular exploration vehicle. WiBotic contributes wireless charging technology, enabling efficient energy transfer under lunar conditions. Bosch focuses on autonomous docking, providing critical systems that ensure the CubeRover(TM) can navigate and connect reliably in this extreme environment. The University of Washington and NASA Glenn Research Center contribute by offering performance characterization and testing of the wireless charging system.

Together, these efforts promise to revolutionize space exploration while paving the way for future innovations in autonomous systems development.

The minds behind the mission — Vivek Jain and his team

One of them is Vivek Jain, a lead expert at Bosch Research. Astrobotic serves as the principal investigator for this project, working closely with Bosch, which contributes its expertise in sensing, software, and autonomous docking for wireless power transmission.

Together, the partners are developing technologies that enable the rovers to navigate the moon with precision — without GPS. To achieve this, Bosch relies on a combination of camera data, Wi-Fi fingerprinting and sensor fusion. These approaches ensure that the rovers operate reliably even under extreme conditions such as intense light or presence of sticky lunar dust. With these innovative solutions, Bosch plays a crucial role in advancing the development of autonomous systems designed for the moon’s demanding environment.

Vivek Jain, Head of the Wireless Connectivity and Sensing group at Bosch Research, Sunnyvale, USA CubeRover(TM) — small, lightweight, and efficient

CubeRover(TM) is the centerpiece of the lunar mission, designed specifically for operation on the moon’s surface. A modular, ultra-lightweight, and compact rover, its smallest form factor weighs less than 5 pounds and is roughly the size of a shoebox. These characteristics enable the simultaneous transport of multiple rovers on a central platform (lander), which lands on the lunar surface and serves as a base station for power and navigation.

This makes missions not only more flexible but also more cost-effective, as multiple rovers can be deployed with a single launch. In addition to its compact size, CubeRover(TM) impresses with its versatility. It can carry scientific instruments such as cameras or spectrometers, opening up new approaches to lunar exploration. With its innovative technology and ability to operate reliably even in extreme environments, it represents a turning point in the exploration of new worlds.

Reaching the destination without GPS — the challenges of navigating the moon

How Bosch develops creative solutions for navigation.

Orientation with visual markers and sensor fusion

How do you navigate on the moon, where GPS is not an option? Bosch has the answer with innovative technologies that guide the CubeRover(TM) safely through the extreme conditions of the lunar surface. The lander, a platform on the moon’s surface, serves as a central base station for the CubeRover(TM), providing energy and orientation. Special visual markers, known as AprilTags, are attached to the lander and function like QR codes. These markers are detected by the CubeRover(TM)’s camera, enabling it to accurately calculate its position and navigate securely.

In addition, the CubeRover(TM) employs sensor fusion, combining camera data with information from motion sensors and wheel speed sensors. This technology ensures stability even on uneven or slippery surfaces — performing reliably amidst dust, intense light, or wheel slips.

Wi-Fi fingerprinting as a backup solution

In addition to visual markers, Bosch uses Wi-Fi fingerprinting to ensure the CubeRover(TM)’s navigation. The lander, the central platform on the lunar surface, emits Wi-Fi signals that the rover receives. Based on the signal strength and characteristics, the CubeRover(TM) determines its position and creates a map of the surroundings.

This method acts as a backup when visual markers are obscured by dust or shadows, ensuring the CubeRover(TM) remains navigable even under challenging conditions. By combining visual markers, sensor fusion, and Wi-Fi fingerprinting, Bosch enables precise navigation – entirely without GPS.

Wireless charging

The small rover presents unique challenges for energy supply. Being too small for large solar panels, the CubeRover(TM) employs an innovative solution: wireless charging. The lander collects solar energy and transfers it wirelessly to the rover.

An additional benefit of this technology is the heat generated during the charging process. This heat is used to protect the rover from the extreme temperatures of the lunar night. Intelligent charging algorithms ensure that the rover aligns its position optimally for efficient energy transfer.

ISO 10218, third edition, was released at the start of 2025. This standard covers industrial robot safety. Typically, this means fixed industrial robots, including what are known as cobots. A HAS consultant assessed the standard, which will hopefully be published shortly in the OJEU (official journal of the European Union) giving a presumption of conformity with all relevant machinery directive clauses.

Note – ISO TC 299 WG 3: avoid using the word cobot, as there is no such thing. The assertion is that the application is collaborative and not the robot. Any robot can work in a collaborative application with the right external equipment, e.g., a laser scanner or 3D TOF may allow implementation

Figure 1: Two parts of the new industrial robot safety standard

I think I started on this committee in 2018, and Ireland hosted a meeting on the committee in 2019, but I believe WG3 was already working on this revision well before that time. The convenor was Roberta Nelson Shea of Universal Robots, which meant we had much experience right there, but there was a lot. I mean a lot, of experience in both the application and design of robots within the group. It also included health and safety professionals, independent assessors, and a human factors expert. It was a well-attended group, with over 50 in some cases, leading to restrictions on how many from each country were allowed to attend. Countries with big teams attending included Canada, Japan, Korea, Sweden, Germany, the USA, the UK, Ireland, Denmark, and Italy…. I must admit, I’m a robot safety expert who has never used a robot. My other major functional safety contributor is on the IEC 61508 committee, where I lead the semiconductor group, including the new IEC 61508-2-1. Therefore, once we strayed into the use of robots, as opposed to their design, I was out of my depth. For this reason, I am sure that the highlights I have chosen below from the new version would be very different from those chosen by someone with a different background.

Figure 2: Excerpt from the Irish papers dated November 2019

My highlights are:

• Removal of mandatory redundancy requirements
• New security guidance
• New comms requirements

Removal of Mandatory Redundancy Requirements

Let’s start with the mandatory redundancy requirements. The older 2011 version required a default SIL 2 with HFT=1 or PL d CAT 3 safety function. This offended me on several levels, including:

• With complex technology, systematic failure modes are more of a concern than random hardware failures
• HFT= 1 and CAT 3 are not even the same thing (CAT 3 allows the impact of diagnostics in achieving single fault tolerance to be considered, HFT does not)
• Modern technology based on semiconductors can be far more reliable than older mechanical technology and with higher diagnostic rates and lower diagnostic test intervals

Figure 3: Graphic showing the 4.43e-7/h portion of the SIL 2,PL d range

Even after many years of debate (yes years and I am not exaggerating) the following was agreed. If you weren’t involved, the number of 4.43e-7/h might seem random. Both PL d and SIL 2 require a failure rate in the range 1e-6/h to 1e-7/h, so it’s just below the midpoint of the range. It’s in the better half, indicating lower-than-average risk. But if lower-than-average was all we required, we could have used 5.0e-7/h. Shown another way, it can be compared to what is traditionally achieved with a CAT 3 architecture. The graphic above also shows it exceeds what is generally considered possible with a CAT 2 (non-redundant) architecture. However, the best way to show it is by highlighting it using ISO 13849-1:2015 Annex K. To get to this number with a CAT 2 architecture (single channel with diagnostics) you need an MTTFd (mean time to failure dangerous) of 62 years and a DC of 90%. It also shows that previously with your CAT 3 architecture a DC of 60% would have been acceptable but that would deliver a much worse PFHd unless you got your MTTFd to at least 43 years and that with CAT 3 and a DC of 90% you can easily reach down into PL e type performance.

It’s good to write this down while I still remember the reasoning. These changes will make it easier to adopt new technologies into robots but reduce the robot cost and increase the robot’s capabilities, which hopefully will all contribute to a higher adoption of robots. Such new technologies might include 3D TOF and novel encoders.

New Security Guidance

Figure 4: 4.43e-7/h shown in comparison to the traditional CAT 3 architecture

My next highlight is the new cyber security guidance. It’s always controversial whether safety standards should include anything on cyber security or whether the two disciplines should remain separate. However, it is good that we added something as the new EU machinery regulation (replacing the old machinery directive) places more emphasis on cyber security than the old machinery regulation. We also now have the CRA . I would have liked to add more emphasis on IEC 62443 compliance, but what we got is good. A cyber security risk assessment is now required, and IEC TS 63074:2023 is called out, which then defers to IEC 62443. I spoke on cyber security for robots at last year’s international robot safety conference in Cincinnati. Unfortunately, the presentations from this excellent conference are not available on the web.

New Comms Requirements

Lastly, in a world with more and more requirements for always being connected, data is the new oil; it is good that the standard now includes requirements for industrial communications. There was nothing in the old version on safety data to be transmitted over a network. Previously, the best guidance would have been in IEC 61508-2010 7.4.11, which mentions a white channel design with no further details and defers to either IEC 61784-3 or IEC 62280/EN 50519 for the black channel designs. The new version of ISO 10218 concentrates on the more common black channel approach and, despite being short, shows how the black channel requirements can be tailored differently for the internal robot network (controller to the various axes) and the external robot network, e.g., controller to a PLC.

This is an area I continue to work on; we are revamping IEC 61508-2 7.4.11 with more details on the white channel in particular, which I think might be especially relevant for robot internal networks since it is more suitable in my view for hard real-time requirements. I have also, for my sins, been appointed as the liaison between IEC TC 65 SC65A(system) and SC 65C.  The black channel will continue to be the most important for the controller to the PLC network, and the 1km range offered by 10BASE-TIL and even Ethernet APL / 2-WISEcould be important here.

Other information I like in the new version includes:

• The long list of safety functions in Annex C
• The allowances for small robots in 5.1.17 (<10kg, <250mm/s, <50N)
• The nice figure in Annex B shows maximum, restricted, operating, and safe-guarded spaces

ISO TC 299 WG 3 is continuing to work on ISO 20218-3, which will give more guidance on the limited information on cyber security within ISO 10218. I don’t know whether ISO 10218 already needs a refresh to allow for machinery regulation.

As EEPROM devices shrink, board space can be freed for exciting uses. However, smaller EEPROM means smaller cell sizes. This in turn means thinner cell oxide layers. These can wear out more easily, raising reliability concerns. Many manufacturers defend against cell wear out with Error Correcting Codes which detect and correct errors. This solution is usually hidden, with no way of knowing whether it’s there or if it was invoked. Thus, ECC should be seen as a safety feature, not a sole reliability solution. That’s why Microchip Technology, with over 30 years of EEPROM experience, has developed a new family of EEPROM with Error Correction Status. ECS alerts users when error correction occurs, indicating that a memory block should be retired. This feature takes error correction one step further, acting as a powerful reliability multiplier for stand-alone EEPROM, and providing transparency and control designers can enjoy.

Error Correction

As mentioned, most new EEPROMs include Error Correcting Codes, typically designed to correct single-bit errors for each specified number of bytes. There are multiple types of ECC used, the most common being Hamming codes. ECC adds parity bits calculated from stored data. When data is read back, the parity bits are recalculated from stored data and compared to the parity bits stored in memory. Discrepancies indicate errors, and the pattern of the discrepancy allows the system to pinpoint and correct single-bit errors, restoring the data and allowing the memory block to continue to be used. However, many EEPROMs don’t indicate when corrections occur, leaving you unaware of deteriorating blocks. ECC then can only be used as a safety feature, giving the application a marginal endurance extension so it may last a bit longer without corrupted data. If you need to know if a block is truly worn out, you can add manual checks to verify memory after each write, but this is resource intensive. Error Correction Status on the other hand solves this challenge because it automatically flags you when a block becomes worn-out, enhancing reliability without needing to invest a large amount of resources.

System Considerations

The advantage of ECS shines the most within wear-leveling routines. How does wear-leveling work? Let’s begin with system design considerations and explain how wear leveling works, then we will show how to use ECS to enhance a wear-leveling routine.

Regardless of whether your EEPROM has ECC or not, it’s crucial to consider its endurance, typically rated at 100,000 cycles for MCU-embedded EEPROM and 1 million cycles for standalone EEPROM at room temperature. Designers must account for this by estimating the number of write cycles over the typical lifetime of the application to determine what size of an EEPROM they need and how to allocate data within the memory.

For instance, consider an industrial power distribution system in a building with four sensors, one for each machine that workers can use when needed. Each sensor generates a data packet per usage session, recording things like energy consumption, session duration and timestamps. Data is stored in the EEPROM until a central server requests a data pull. The system is designed to pull data frequently enough to avoid overwriting existing data within each packet. Assuming a 12-year application lifespan and an average of 400 daily packets per sensor, the total cycles per sensor will reach 1.752 million, greatly surpassing the typical EEPROM endurance rating. To address this, you can create a software routine to spread wear out across the additional blocks (assuming you have excess space). This is called wear-leveling.

Wear-Leveling: Dynamic and Static

To implement wear-leveling, you can purchase an EEPROM twice as large, allowing you to allocate 2 blocks per sensor, providing up to 2 million cycles per sensor. This offers a buffer of additional cycles if needed (an extra 248 thousand cycles per sensor).

You will then need some way to know where to write new data to spread the wear. While you could write each block to its 1-million-cycle-limit before proceeding to the next, this approach may lead to premature wear if some sensors generate more data than others. If you spread the wear evenly across the EEPROM, the overall application will last longer. Figure 1 illustrates the example explained above, with four meters sending data packets (in purple) back to the MCU across the communication bus. The data is stored in blocks within the EEPROM. Each block has a counter in the top left indicating the number of erase-write cycles it has experienced.

Figure 1

There are two types of wear-leveling: dynamic and static. Dynamic wear-leveling is simpler, spreading wear over frequently changing memory blocks but can result in uneven wear. Uneven wear caused by this type of wear-leveling is illustrated in Figure 2. The other type: static wear-leveling, spreads wear across the entire EEPROM, extending the life of the entire memory. Static wear-leveling requires more CPU overhead; however, it will produce the highest endurance for the life of the application.

Figure 2

Wear-leveling involves monitoring each memory block’s write cycles and allocation status, which itself can cause wear in non-volatile memory. To deal with this, one option is to store this information in your MCU’s RAM, which doesn’t wear out. Since RAM loses data on power loss, you may consider designing a circuit to detect power loss early, allowing time to transfer current register states to NVM.

Implement Wear-Leveling in Software

In general, a software approach to wear-leveling is to create an algorithm which directs writes to the block with the fewest previous number of writes to spread wear. In static wear-leveling specifically, data is stored in the least-used location not currently allocated for anything else, and data will be swapped to new locations if the cycle difference between blocks is too large. Each block’s write cycles are tracked with a counter, and blocks are retired when they reach their maximum endurance rating.

Wear-leveling effectively reduces wear and improves reliability, allowing each block to reach its maximum specified endurance (Figure 3). However, endurance specifications are only rough indicators of the physical life of the block and don’t include early failures. Also, many blocks will last much longer in the real-world than their endurance ratings allow for. To ensure even higher reliability, additional checks are needed. One method is to read back and compare the block just written to the original data, which requires bus time, CPU overhead and additional RAM. This readback should occur for every write, especially as the number of writes approaches the endurance limit, to detect cell wear-out failures. Without readbacks, wear-out and data corruption may go undetected. The following software flowchart illustrates an example of static wear-leveling, including the readback and comparison necessary to ensure high-reliability. This implementation has the disadvantage of spending significant system resources on reliability.

Figure 3

Using Error Correction Status with Wear-Leveling

Error Correction Status enables a new data-driven approach to wear-leveling and significantly enhanced reliability without the need for full data readbacks.

ECS indicates when a single-bit error has been detected and corrected. This allows you to check a status register to see if ECC was invoked, reducing the need for full memory block readbacks (Figure 4). When an error is detected, the block can be retired, providing data-based feedback on memory wear-out instead of relying on a blind counter. This eliminates the need to carefully estimate memory lifespan and is beneficial for systems that experience vast shifts in their environments over their life, like dramatic temperature and voltage variations which are common in the manufacturing, automotive and utilities industries. This approach allows you to extend memory cell life beyond the datasheet endurance specification all the way to true failure, potentially allowing you to use the device much longer than before.

Figure 4

This data-driven approach to wear-leveling is more reliable than classic wear-leveling because it uses actual data instead of arbitrary counts—if one block lasts longer than another, you can continue using that block until cell wear out. It also reduces bus time, CPU overhead and required RAM, which in turn lowers power consumption and improves system performance. Your software flow can now be updated to accommodate this new status indicator (Figure 5).

Figure 5

As illustrated in the flowchart, using an ECS bit simplifies the software flow by eliminating the need to read back data, store it in RAM and perform comparisons, freeing resources to create conceptually simpler software. Although a data readback is still required to evaluate the status bit, the data can be ignored, reducing RAM and CPU overhead. The frequency of status bit checks depends on block size and the smallest file size the software handles.

The following devices offer ECS and are currently released and available for order:

• I2C EEPROMs: 24CSM01 (1 Mbit), 24CS512 (512 Kbit), 24CS256 (256 Kbit)
• SPI EEPROMs: 25CSM04 (4 Mbit), 25CS640 (64 Kbit), 25CS320 (32Kbit)

The overall benefit of ECS is significant and will allow you to see cell health in a way you could not before. Some of the advantages are:

• Maximize EEPROM block lifespan by running cells to failure
• Option to remove full block reads to check for data corruption, freeing up time on the communication bus
• If wear-leveling is not necessary or too burdensome to the application, the ECS bit serves as a quick check of memory health, facilitating the extension of EEPROM block lifespan and helping to avoid tracking write cycles

Reliability Improvements with ECS

Implementing error correction with a status indicator revolutionizes reliability and extends device life, especially within wear-leveling schemes. This advancement is a game-changer for automotive, medical and other safety-critical applications, offering unparalleled reliability. Designers striving for excellence will find this approach indispensable in creating top-tier systems that stand the test of time. Remember, using our new CS EEPROM will allow you to take hold of your reliability destiny. For more information, be sure to check out our CS family of EEPROM products.

Gate-induced drain leakage (GIDL) presents a major challenge in scaling DRAM technology.

DRAM serves as the backbone of modern computing, enabling devices ranging from smartphones to high-performance servers. As the demand accelerates for higher density and lower power consumption in memory devices, innovation in reducing DRAM leakage currents and enhancing performance becomes essential. One significant challenge in scaling DRAM technology is GIDL, a primary source of standby charge loss. This article explores how a DWMG structure in DRAM buried word-line (BWL) can mitigate GIDL. By leveraging a full-scale process integration model that supports electrical analysis, we demonstrate how this approach reduces leakage current while maintaining robust device performance.

The Challenge of GIDL in Modern DRAM

GIDL is primarily caused by band-to-band tunneling (BTBT) at the drain junction under high electric field conditions. This phenomenon not only increases off-state leakage currents but also degrades memory state retention time in DRAM cells, particularly as feature sizes shrink below 20 nm.1

Factors such as thinner gate oxides and higher doping concentrations exacerbate GIDL, creating a synergistic effect that makes it a critical problem in designing low-power, high-density DRAM.2

Figure 1: (a) Gain-induced drain leakage during pre-charge mode in DRAMs and (b) the mechanism of trap-assisted band-to-band tunneling3

The Solution

The introduction of a dual work-function metal gate structure provides a compelling solution to this challenge. By segmenting the buried word-line gate into regions with distinct work functions, the electric field along the channel is precisely controlled. Examples of some dual work-function metal gate structures are shown in Figure 2.

This structure suppresses BTBT generation, thereby reducing GIDL without compromising drive current or threshold voltage (Vt). As a result, this design is well-suited for advanced DRAM nodes.4,5

DWMG Alignment with Industry Trends

The DWMG approach aligns with broader semiconductor trends emphasizing advanced gate designs and channel engineering. Our study applies this innovation to DRAM technology, addressing GIDL challenges while preserving key performance metrics. Similar methods have been successfully implemented in FinFETs6 and tunnel FETs7 to reduce leakage and improve subthreshold slopes.

Leveraging Process Integration Modeling for Insights

Our process integration modeling platform (SEMulator3D) with built-in electrical analysis capabilities played a pivotal role in evaluating the DWMG design. This tool allowed us to:

1. Simulate the full process flow of a DRAM cell array, from active area formation to capacitor integration (Figure 3a).
2. Focus on the BWL transistor by extracting and refining a specific transistor for electrical characterization (Figure 3b–d).
3. Analyze the interactions between process parameters—such as gate work-function, oxide thickness, and doping profiles—and their impact on electrical performance.

This simulation framework provided a holistic view of integration challenges and revealed the effectiveness of DWMG in reducing current leakage.

DWMG Design and Simulation Results

The DWMG structure is realized by splitting the gate into upper and lower regions with distinct work functions in the upper region’s metal gate of 3.5eV, 4.1eV, and 4.7eV (Figure 4). The device simulation considers the models of doping/field-dependent mobility, Shockley-Read-Hall (SRH) generation/recombination, and trap-assisted band-to-band tunneling effects.

The drift-diffusion equation is solved to obtain Idrain vs. Vgate curves, both in the linear and saturation regimes. The substrate current is measured (virtually) to determine the GIDL leakage amount.

Figure 4: A cross-section of the device simulation structure and metal gate work-function split conditions

Key results include the following:

1. Leakage reduction (Figure 5): The low and high work-function regions, in the upper gate and lower gate, respectively, create a more relaxed electric field distribution than the same work-function without the DWMG, which suppresses BTBT at the drain junction and in turn reduces leakage current.

Figure 5: Electric field and BTBT rate at the gate-drain overlap region (left) and a 2D field view of BTBT rate at Vg=-2.5V and Vd=+1.5V bias conditions (right).

2. Preserved device performance (Figure 6): Despite the GIDL reduction (I_subtrate), critical IV characteristics in both linear (Idlin_Vg) and saturation (Idsat_Vg) regimes remain intact when using the DWMG, ensuring reliable operation during read and write cycles.

Figure 6: Id vs. Vg in linear regime @Vd=0.1V (left), Id vs. Vg in saturation regime @ Vd=1.5V (middle), and Isub vs. Vg @Vd=1.5V (right).

3. Process dependency (Figure 7): Gate oxide thickness and doping concentration significantly influence performance. For instance, thinner oxides improve field control but increase BTBT risk due to the reduced barrier width. Similarly, higher doping improves modulation capabilities but exacerbates BTBT by increasing the electric field intensity, which accelerates tunneling processes.

Figure 7: Isub and max BTBT rate vs. gate oxide thickness (left) and Isub and max BTBT rate vs. source/drain doping (right).

Advantages of Combining Device Electrical Analysis with Process Integration Modeling   

Performing device electrical analysis during process integration modeling can enable the following types of advanced analyses that identify design-technology trade-offs:

• Electrical pathfinding: This type of analysis can be used to rapidly explore combinations of gate work-functions, oxide thicknesses, and doping profiles to pinpoint optimal designs. This approach has the potential to minimize the cost and time of physical experiments while reducing risks associated with late-stage failures.
• Variability analysis: Statistical simulations can identify the impact of process variations—such as gate oxide non-uniformity and doping fluctuations—on GIDL and IV characteristics. This type of analysis highlights critical design margins and has the potential to provide feedback on process optimization (such as active area formation) from very early process development stages.

The Future of DWMG and DRAM

The dual work-function metal gate (DWMG) is a robust, scalable solution for mitigating GIDL in DRAM technology. By optimizing the electric field distribution, this design effectively reduces leakage currents while maintaining critical IV performance. Process integration modeling combined with electrical analysis capabilities is instrumental in demonstrating the ability to reduce leakage current using DWMG, offering a comprehensive framework for addressing design and integration challenges.

Future research efforts could include:

• Integrating DWMG designs with high-k dielectrics or advanced junction engineering to further enhance leakage control.
• Assessing the impact of scaling trends, such as smaller metal pitches and EUV lithography, on DWMG performance.
• Developing predictive models for variability in advanced DRAM nodes.

Broadcom’s portfolio of automotive Ethernet switches are built not only for today’s automotive network, they’re scalable for the network of the future.

Automakers have used Broadcom’s standard automotive switches for more than a decade to route data between various sensors, processing units, and actuators within the vehicle. As automakers transition from domain-based to zonal architectures, pre-planning allows the architectures to scale to newer features and benefits.Software-defined vehicles, or SDVs, have the connectivity and processing power to secure, monitor, upgrade, and update vehicle capabilities. The software for different computing functions, such as driver assist, infotainment, body control, and instrumentation, can all be distributed across different boards and processors. Sensor data can flow to multiple zones/boards versus being directly connected. It is the scalability of Ethernet hardware that allows an SDV to be improved after purchase. So, what features should you look for in a switch to support SDVs?

Network Scalability for SDVs

The first item to examine is the type of system on chip, or SoC, that is being used for compute processing in your architecture. New classes of automotive SoCs allow application processing, real-time processing, AI compute, and safety functionality in a single device. Zonal and central compute electronic control units (ECUs) can take advantage of these scalable SoCs. These SoCs have multiple multi-gigabit interfaces to the network to gather and transmit all the data they need to process. For example, AI models for autonomous drive systems can be updated to improve camera recognition and safety. As new software features are added, the amount of data sent over these SoC interfaces will increase. Just as the SoCs are optimized and designed to scale over time to handle larger compute and network needs, the Ethernet network must be designed from the start to support future needs. The automotive Ethernet switch must support multiple connections to the SoCs at the maximum line rate needed. The switch should also be able to support the scalability of each interface from 1Gbps to 10Gbps. If the SoC supports PCIe interfaces with virtualization, then the switch needs to support virtualization as well.

As the software feature workloads get distributed between compute devices, there will be a need for network performance optimizations and time-sensitive provisioning. SDVs will collect data across the network for data analytics and health monitoring. The Ethernet switches will use their packet filters to monitor specific traffic flows at line rate. Captured motor efficiency data, Ethernet network health, and autonomous drive data for AI model improvement can all traverse the Ethernet backbone to the car’s cloud connection. Dynamic configuration of the automotive Ethernet switches allows the automaker to scale the needed resources efficiently over time. Automotive Ethernet switches need to have the bandwidth scalability and timing control to handle future network needs.

As port count requirements for an ECU increase, the automotive Ethernet switch chip must be able to handle all the ports with a single die. A switch chip that uses more than one smaller switch die in a single package can cause numerous issues. The stacking or cascading switch cores have higher latency as the Ethernet packets must be stored and forwarded through each switch die. The high-speed interface between these embedded dies becomes a bottleneck for traffic that must flow from a port on one die to the port on the other die. Time synchronization becomes trickier as multiple gPTP protocol stacks are run inside the single package. Scalability is a key feature enabled effectively with a monolithic die based switch.

As mentioned in our blog,”Securing software-defined vehicles with zonal E/E architectures,” protecting SDVs using zonal electrical/electronic architectures is critically important. The SDV architecture requires a multilayer security approach. The switches need to boot authenticated images securely, and they must allow only authenticated images to be loaded during over-the-air updates. Since software-based protection is challenging at faster Ethernet speeds, MACsec packet authentication and encryption allows line-rate protection in hardware at speeds up to 10 Gbps. In addition, both DOS protection and packet filtering are needed in hardware. Additional levels of protection can be taken in hardware that are unique to an automotive network architecture. An automotive network is fixed, unlike an SMB or enterprise Ethernet network. A port on the switch connected to a RADAR will always be connected to that RADAR in every car. If the unique address of the RADAR on an Ethernet packet is ever seen ingressing on another port, then it is known that someone is spoofing that address, and the port should be quarantined. The same can be said if a second address is seen on the RADAR port, as there should only be one device connected to that port. The security features should be implemented by dedicated hardware in the switch with software running on the internal processor subsystem handling any exceptions. This enables all of the security functionality at line rate and makes the intrusion detection and prevention software clients to be efficient and effective.

One secret behind the success of modern industrial automation is the power of 3D vision. Traditional 2D sensors can only provide flat images, creating limitations in their effectiveness in applications like device inspection. They can read a barcode which may contain the items’ dimensions but cannot independently gauge true shape and size, or any potential dents, defects or irregularities. In addition, 2D readings are at the mercy of lighting conditions, which may obfuscate or distort important areas of interest.

A breakthrough to these constraints can be done with depth sensing, processing the Z-axis in 3D, much like human vision. Now, depth cameras can tell the fullness of an object, perform precise inspections on devices, and even detect subtle facial features for applications such as access control. Thanks to these capabilities, 3D vision is a game-changer across industries – from defense and aerospace to medical, automotive and micro-technology. Whether it’s obstacle detection, facial recognition, self-driving or robotic assistants, depth sensing is the key to modern industrial automation.

Depth sensing, however of type, relies on active or passive visual protectionism. Depth sensing based on passive componentular requires highly calilytic stereo sensors and parallax, very similar to the human eye. Active sensing uses an emitted light beam towards their targets and uses the reflected energy to determine depth. This requires an energy emitter, but offers advantages like penetrating clouds/smoke, 24/7 operation and more deterministic operation.

There are several active directional techniques: direct time-of-flight (dToF), indirect time-of-flight (iToF), structured light and active stereo. Indirect time-offlight uses phase shift between the transmitted and received signals to calculate distance – it’s very accurate and the understanding hardware is simple.

In this blog you will learn about onsemi’s latest family addition, Hyperlux ID has made significant advances in iToF technology and these advances can be utilized to improve depth sensing in current industrial and commercial applications.

Existing iToF Technology Constraints Reduce Widespread Adoption

iToF sensing lies at the heart of many applications. One such popular application is face recognition as seen on various smartphones. However, this access control feature can only function at close range. Other applications that use iToF include machine vision (MV), robotics, augmented reality/virtual reality (AR/VR), biometrics and patient monitoring. Currently these applications are restricted to innulin use at close range (< 5m) with stationary objects that do not require high resolution. Several challenges restrict the potential scope of iToF technology. Among these are motion, the overhead and complexity of the hardware and data processing architecture and the need for meticulous calibration.

These significant hurdles either force engineers to implement complex 3D and expensive solutions to obtain depth, or simply to not acquire depth information at all. With remarkable innovations, onsemi introduces the Hyperlux ID family.

Hyperlux ID family that enables the benefits of iToF without previously noted restrictions. Hyperlux ID’s iToF implementation can now enable a more widespread adoption of this important technology.

Detailing the Hyperlux ID Advances

Onsemi’s Hyperlux ID sensing family initially consists of two 1.2 megapixels (MP) iToF products, the AF0130 and AF0131. This family provides advanced sensor performance and development in four critical areas:

1. Receiving reliable depth information with moving objects

Achieving optimal resolution/depth distance with high accuracy

3. Reducing cost and size
4. Decreasing calibration time

Each of the aforementioned areas and improvements are further detailed.

Momentum Motion Artifacts

To enable more widespread adoption, iToF sensors need to function well with moving objects, so they can produce accurate results without motion. As mentioned, iToF sensing on light reflections using four or more different phases to calculate depth. Nearly all existing iToF sensing solutions in the marketplace do not capture and process these phases simultaneously provide which issues with moving objects. Designed with a unique proprietary integration and readout structure, the Hyperlux ID depth sensor uses global shutter with on-chip storage and real-time processing to enable fast-moving object capture applications such as conveyor belt operation, robot arms, surveillance, collision collision, attachment detection and more.

iToF Applications in Warehouse Increased Resolution = Higher Accuracy and Expanded Depth

Most iToF sensors on the market today have only VGA resolution, which hinders their accuracy, and in turn, limits their applications. One reason VGA is more prevalent is due to the complex phase capture and data intensive processing mentioned prior. In contrast, the Hyperlux ID sensors are designed with 1.2 MP resolution (1280×960) using a high performance 3.5 μm back-side (BSI) pixel. As a product of its increased resolution over VGA, the Hyperlux ID sensor offers the additional critical advantage of expanded range depth. , at closer distances high-precision accuracy is provided and wider-angle optics can be used.

With higher resolution, the Hyperlux ID sensors also deliver improved quantum efficiency and reduced depth jitter. Taken together, these enhancements mean new applications for iToF sensors where high resolution and expanded depth are paramount, such as gesture recognition, quality control/inspection and access control.

Existing iToF solutions (left) vs onsemi’s new advanced Hyperlux ID iToF (right) Longer Range

As a product of increased resolution, the Hyperlux ID depth sensor can measure depth over a much greater range compared to other iToF sensors currently available. While current iToF offerings have an indoor range of less than 10 meters, the Hyperlux ID iToF sensor family can reach up to 30 meters. The usage of a high-performance global shutter pixel enables a full sensor array to closely align to active infrared lighting, which in turn limits noise provides from other infrared sources which are common indoor lights and most challenging of all – the sun.

Easier Calibration and Development

Accurately record and calculating phase differences in iToF sensors require precise calibration, an extremely time-consuming process. To ease this, we have developed a proprietary method that makes Hyperlux ID sensors easier to calibrate and thus faster to set up.

To aid in development, onsemi has constructed an easy-to-use development kit that includes a baseboard, a head sensorboard and a laser board. The kit can be used both indoors and outdoors with a range of 0.5 – 30 meters. It can produce depth maps, 3D point clouds, phase-out and depth-out data from an image.

Activated, by using spread-spectrum techniques many iToF (and other infrared-enabled devices) sensors can be used in the same system without worrying of other interference devices.

onsemi’s iToF Sensors Do More for Less

iToF sensors are excellent at making accurate 3D depth measurements, which have won them a solid place in industrial and commercial applications. With remarkable improvements in performance and design simplification, onsemi’s Hyperlux ID depth sensors open a new world of applications for iToF sensing depth.

Compared to iToF sensors on the market today, Hyperlux ID depth sensors work more effectively with objects in motion, outdoors and at greater distances. In addition, due to their novel design, Hyperlux ID depth sensors are more cost-effective, take up less board real estate and are easier to work with.

The Hyperlux ID family of depth sensors consists of two products: the AF0130 and AF0131. The AF0130 includes built-in depth processing while the AF0131 does not, for customers who prefer to use their own original algorithms.

Future-proof quality assurance for power electronics through sintering paste inspection with multi-line SPI

Higher operating temperatures, thinner interconnection layers, 10 times the longevity – the advantages of sintering pastes over solder pastes have long been recognized in the field of power electronics. Not least for this reason, sintering pastes are preferred in system-critical technologies such as “green energy” and e-mobility. Here, for example, IGBTs have become the central component in converters for all types of electric drives: wind turbines, solar power generation, battery charging – hardly any future technology would be conceivable without the “all-rounder” sintering paste. However, sintering is more prone to errors than soldering paste printing. Furthermore, defects are more difficult to detect and rectify – critical failures in the field are the result. To avoid this, GÖPEL electronic has now added an inspection system specifically for sintering paste to its Multi Line platform.

The Multi Line SPI is a cost-effective 3D inline system for automated inspection of sintering paste. Based on the Multi Line platform, it is a customized solution for small and medium-sized companies with high quality standards; it can also be used for solder pastes. The telecentric 3D camera module is used to inspect solder and sinter paste without shadows for shape, area, coplanarity, height, bridges, volume and X/Y offset. Equipped with two digital fringe projectors for shadow-free 3D image capturing, it has a resolution of 15µm/pixel, a height measurement accuracy of 1µm and a height resolution of 0.2 µm. This means that measurement values can be obtained precisely and repeatedly.

Generation of an inspection program for sinter paste inspection takes only a few minutes: CAD data or a reference layout is sufficient. Users who already use GÖPEL electronic software for programming SMD, THT or CCI systems can learn the additional sinter paste functions with little training. In addition, the data import, verification and statistics software are identical to the other inspection systems from GÖPEL electronic. This is where the platform concept of the Multi Line series really pays off: the uniform, powerful operating and evaluation software across all devices reduces training and programming effort, enabling flexible and optimized staff deployment planning.

• Validates the performance of AI infrastructure by emulating real-world workloads
• Evaluates how new algorithms, components, and protocols improve the performance of
  AI training
• Adjusts and optimizes the parameters of both AI workloads and system infrastructure without investing in expensive large-scale deployments

Keysight Technologies, Inc. introduces Keysight AI Data Center Builder, an advanced software suite that emulates real-world workloads to evaluate how new algorithms, components, and protocols impact the performance of AI training.KAI Data Center Builder’s workload emulation capability integrates large language model and other artificial intelligence model training workloads into the design and validation of AI infrastructure components – networks, hosts, and accelerators. This solution enables tighter synergy between hardware design, protocols, architectures, and AI training algorithms, boosting system performance.

AI operators use various parallel processing strategies, also known as model partitioning, to accelerate AI model training. Aligning model partitioning with AI cluster topology and configuration enhances training performance. During the AI cluster design phase, critical questions are best answered through experimentation. Many of the questions focus on data movement efficiency between the graphics processing units. Key considerations include:

• Scale-up design of GPU interconnects inside an AI host or rack
• Scale-out network design, including bandwidth per GPU and topology
• Configuration of network load balancing and congestion control
• Tuning of the training framework parameters

The KAI Data Center Builder workload emulation solution reproduces network communication patterns of real-world AI training jobs to accelerate experimentation, reduce the learning curve necessary for proficiency, and provide deeper insights into the cause of performance degradation, which is challenging to achieve through real AI training jobs alone. Keysight customers can access a library of LLM workloads like GPT and Llama, with a selection of popular model partitioning schemas like Data Parallel, Fully Sharded Data Parallel, and three-dimensional parallelism.

Using the workload emulation application in the KAI Data Center Builder enables AI operators to:

• Experiment with parallelism parameters, including partition sizes and their distribution over the available AI infrastructure
• Understand the impact of communications within and among partitions on overall job completion time Identify low-performing collective operations and drill down to identify bottlenecks
• Analyze network utilization, tail latency, and congestion to understand the impact they have on JCT

The KAI Data Center Builder’s new workload emulation capabilities enable AI operators, GPU cloud providers, and infrastructure vendors to bring realistic AI workloads into their lab setups to validate the evolving designs of AI clusters and new components. They can also experiment to fine-tune model partitioning schemas, parameters, and algorithms to optimize the infrastructure and improve AI workload performance.

Ram Periakaruppan, Vice President and General Manager, Network Test & Security Solutions, Keysight, said: “As AI infrastructure grows in scale and complexity, the need for full-stack validation and optimization becomes crucial. To avoid costly delays and rework, it’s essential to shift validation to earlier phases of the design and manufacturing cycle. KAI Data Center Builder’s workload emulation brings a new level of realism to AI component and system design, optimizing workloads for peak performance.”

KAI Data Center Builder is the foundation of the Keysight Artificial Intelligence architecture, a portfolio of end-to-end solutions designed to help customers scale artificial intelligence processing capacity in data centers by validating AI cluster components using real-world AI workload emulation.

Keysight will showcase KAI Data Center Builder and its workload emulation capabilities in booth 1301 at the OFC 2025 conference, April 1-3, at the Moscone Center, San Francisco, California.

As vehicle architectures transition to hybrid and electric models, conventional battery systems are increasingly being supplemented or replaced by 48 V power sources. This shift is expected to become the new standard for future electric vehicles, as 12 V and 24 V power net systems reach their limits. 48 V systems enable advanced features, enhance passenger comfort, and improve efficiency by reducing currents and simplifying wire harness complexity. Additionally, the electrification of both primary and secondary power distribution systems requires replacing conventional relays and fuses. To support this development, Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) is launching the Power PROFET + 24/48V switch family, developed for the requirements of modern vehicle power systems.

The Power PROFET + 24/48V switch family is housed in a compact, TO leadless package and includes two high-side switch variants: the BTH50030-1LUA with an RDS(ON) of 3.0 mΩ and the BTH50015-1LUA with an RDS(ON) of 1.5 mΩ, which enables minimal power losses in high-current applications. The devices are ideal for the demanding requirements of today’s automotive electrical systems and for commercial and hybrid vehicles, as well as the next generation of electric cars, where they enable a safer, greener and more comfortable driving experience.

One of the key benefits of the Power PROFET + 24/48V switch family is their efficiency and space-savings capabilities. The switches are highly integrated and offer resettable and diagnostic features. They are designed for optimal performance in demanding environments and offer a low on-resistance of just 1.5 mΩ. This makes them ideal for high-current applications and robust enough to withstand the conditions in hot cabin and engine compartments. With more than 1,000,000 switching cycles, the switches far exceed the average 200,000 cycles of conventional relays and offer excellent reliability.

Built-in protection and diagnostic functions such as short-circuit, over-current and over-temperature protection provide safety of the device. Diagnostic signals enable advanced fault detection and increase the reliability of the entire vehicle by preventing failure modes in the power supply network. The switches are housed in an 8-pin TO leadless package, reducing the footprint by 23 percent compared to, for example, D2PAK packages with similar thermal performance. The accuracy of the load current sense is ±5 percent after calibration and can be easily determined by reading an analog voltage at the IS pin. In addition, the switch family is PRO-SIL ISO switch 26262-ready and comes with a safety application note that supports the evaluation of hardware elements according to ISO 26262.

To enable seamless integration, the Power PROFET + 24/48V family is supported by the online simulation tool Infineon Automotive Power Explorer which is available in the Infineon Developer Center. The tool helps to calculate intrinsic fuse characteristics and visualize the sense current range for specific load currents, ensuring accurate and efficient implementation.
