Reducing Component Counts, Self-Protecting Devices Combine Energy Handling to 340 J With R25 Values to 1.5 kΩ and High Voltages to 1200 VDC

Vishay Intertechnology, Inc. has introduced a new series of inrush current limiting positive temperature coefficient (PTC) thermistors. Designed to increase performance in active charge and discharge circuits for automotive and industrial applications, Vishay BCcomponents PTCEL High Energy series devices combine maximum energy handling to 340 J — five times higher than competing devices at high ambient temperatures — with a wide range of resistance at 25 °C (R25) values and high voltage capabilities.

Featuring R25 values from 150 Ω to 1.5 k Ω, the thermistors released today enable increased efficiency and high maximum voltages of 1200 VDC. The devices offer high energy handling capabilities at higher ambient temperatures — 180 J at 85 °C and 130 J at 105 °C — allowing designers to save space and lower costs by utilizing fewer components in their circuits. With their high switching temperature and operation to +105 °C, the PTCEL High Energy series offers a heat capacity to 2.6 J/K for all resistance values.

AEC-Q200 qualified and self-protecting — with no risk of over-heating — the thermistors provide current limitation and overload protection in AC/DC and DC/DC converters; DC-Link, battery management, and emergency discharge circuits; on-board chargers; home energy storage systems; heat pumps; motor drives; and welding equipment. For these applications, the devices withstand > 100 000 inrush power cycles and are highly resilient against non-switching peak power up to 25 kW.

The PTCEL High Energy series barium titanate thermistors consist of a ceramic pellet soldered between two tinned CCS wires and coated with a UL 94 V-0 compliant high temperature silicone lacquer. The devices are available in tape on reel packaging and can be automatically handled by pick and place equipment for lower placement costs. The thermistors offer a standard leadwire pitch of 10 mm, with leadwire pitches of 5.0 mm and 7.5 mm also available. SPICE and 3D models for the RoHS-compliant devices are available.

STPOWER Studio 4.0 just became available and now supports three new topologies (1-phase full bridge, 1-phase half-bridge, and 3-phase 3-level T-NPC) to cover significantly more applications. Previously, the online simulation tool only offered a 3-phase 2-level topology for motor drivers and photovoltaic inverters, which are some of the most popular use cases. Thanks to the robustness of the underlying architecture that ST recently updated and brought to the web, we are now able to build on top of the existing platform to make STPOWER Studio more versatile and assist more engineers in designing a more comprehensive range of power stages.

What is STPOWER Studio? A unique simulator STPOWER Studio delivers extensive analyses quickly and easiily

STPOWER Studio, a component of eDesignSuite, specializes in thermo-electrical simulations. As eDesignSuite transitioned to HTML5 to enhance its user interface, STPOWER Studio benefited from the same underlying architecture, enabling more powerful simulations. It stands out in the industry as one of the few simulators capable of adjusting power losses according to the junction temperature at the moment of the simulation, providing a more accurate representation of real-world usage. Some competitors traditionally use a fixed value for the junction temperature, leading to over- or underestimated losses. Thanks to our dynamic junction temperature, users get more accurate results.

STPOWER Studio can simulate up to hundreds of seconds per step with Steady State off, which gives engineers enough time to see how their power stage would ramp up and stabilize. They can also run simulations with or without heat sinks, which will help them anticipate form factor and heat dissipation requirements. Users simply select the ST family of devices (ACEPACK or SLLIMM) and the component they will use in their design. Under Setting, designers can tweak the gate resistor values and some thermal properties. Finally, under I/O, users can adjust their mission profile by defining various steps with values such as the output power or the current level, among other things.

A design assistant

Let’s take the example of an engineer designing a large motor driver for industrial applications, an inverter for a photovoltaic converter, or an HVAC system. In our example, the motor would use a DC Link voltage of 650 V and an RMS Phase Current of 10 A. For a quick simulation, users can use Steady State ON to analyze performances after reaching a thermal steady state. Then, by choosing Steady State OFF, users can set the duration of the simulation step for a more detailed analysis. Obviously, it will require more computing power on the server and take longer to generate. However, ST reduced rendering times by a factor of 10 over the last releases of STPOWER Studio.

What’s new in STPOWER Studio 4.0? 1-phase full bridge STPOWER Studio supports heatsink sizing and monitoring data on non-testable parameters

The new version of STPOWER Studio features three new topologies. The 1-phase full bridge will fit single-phase photovoltaic converters or uninterruptible power supplies. As more residential homes and buildings increasingly rely on renewable energy, the ability to store solar energy in batteries is increasingly in demand. Hence, we wanted to ensure that engineers could more rapidly test their designs and reduce their time to market. Similarly, engineers working on an uninterruptible power supply can very quickly anticipate what their design will look like if they adopt an STPOWER device.

1 phase half bridge

Since STPOWER Studio supports a one-phase full bridge topology, it made sense to offer a one-phase half-bridge. This structure is common in DC-AC conversion for smaller solar inverters or motor drivers. Engineers also combine single-phase half-bridge topologies when designing a one-phase to three-phase converter. In fact, while the current version of the simulator focuses solely on DC-AC systems, we are evaluating the addition of DC-DC applications and will update this blog post with more information as they become available.

3-phase 3-level T-NPC Extensive analyses in STPOWER Studio

Finally, the 3-phase 3-level T-NPC (T-type Neutral Point Clamped) is increasingly popular because it improves overall efficiency by reducing switching losses thanks to a mechanism that clamps the input voltage at its halfway point. Consequently, only half of the input voltage is applied to each switch, which reduces switching losses. This creative approach greatly benefits high-power systems, such as photovoltaic inverters, power factor inverters, or motor drivers, while ensuring the overall design remains relatively small.

Infineon Technologies AG has announced the launch of a new family of high-voltage discretes, the CoolGaN Transistors 650 V G5, further strengthening its Gallium Nitride (GaN) portfolio. Target applications for this new product family range from consumer and industrial switched-mode power supply (SMPS) such as USB-C adapters and chargers, lighting, TV, data center, and telecom rectifiers to renewable energy and motor drives in home appliances.

The latest CoolGaN generation is designed as a drop-in replacement for the CoolGaN Transistors 600 V G1, enabling rapid redesign of existing platforms. The new devices provide improved figures of merit to ensure competitive switching performance in focus applications. Compared to key competitors and previous product families from Infineon, the CoolGaN Transistors 650 V G5 offer up to 50 percent lower energy stored in the output capacitance (Eoss), up to 60 percent improved drain-source charge (Qoss) and up to 60 percent lower gate charge (Qg). Combined, these features result in excellent efficiencies in both hard- and soft-switching applications. This leads to a significant reduction in power loss compared to traditional silicon technology, ranging from 20 to 60 percent depending on the specific use case.

These benefits allow the devices to operate at high frequencies with minimal power loss, resulting in superior power density. The CoolGaN Transitors 650 V G5 enable SMPS applications to be smaller and lighter or to increase the output power range in a given form factor.

The new high-voltage transistor product family offers a wide range of RDS(on) package combinations. Ten RDS(on) classes are available in various SMD packages, such as ThinPAK 5×6, DFN 8×8 , TOLL and TOLT. All products are manufactured on high-performance 8-inch production lines in Villach (Austria) and Kulim (Malaysia). In the future, CoolGaN will transition to 12-inch production. This will enable Infineon to further expand its CoolGaN capacity and ensure a robust supply chain in the GaN power market, which is expected to reach $2 billion by 2029, according to Yole Group.

A demo featuring the CoolGaN Transistors 650 V G5 will be showcased at electronica 2024 in Munich from November 12 to 15 (hall C3, booth 502).

Devices Combine High Peak Output Currents to 4 A With High Operating
Temperatures to +125 °C and Low Propagation Delay of 200 ns

Vishay Intertechnology, Inc. has introduced two new IGBT and MOSFET drivers in the compact, high isolation stretched SO-6 package. Delivering high peak output currents of 3 A and 4 A, respectively, the Vishay Semiconductors VOFD341A and VOFD343A offer high operating temperatures to +125 °C and low propagation delay of 200 ns maximum.

Consisting of an AlGaAs LED optically coupled to an integrated circuit with a power output stage, the optocouplers released today are intended for solar inverters and microinverters; AC and brushless DC industrial motor control inverters; and inverter stages for AC/DC conversion in UPS. The devices are ideally suited for directly driving IGBTs with ratings up to 1200 V / 100 A.

The high operating temperature of the VOFD341A and VOFD343A provides a higher temperature safety margin for more compact designs, while their high peak output current allows for faster switching by eliminating the need for an additional driver stage. The devices’ low propagation delay minimizes switching losses while facilitating more precise PWM regulation.

The optocouplers’ high isolation package enables high working voltages up to 1.140 V, which allows for high voltage inverter stages while still maintaining enough voltage safety margin. The RoHS-compliant devices offer high noise immunity of 50 kV/µs, which prevents fail functions in fast switching power stages.

Many industrial applications today are transitioning to higher power levels with minimized power losses, which can be achieved through increased DC link voltage. Infineon Technologies AG addresses this challenge by introducing the CoolSiC Schottky diode 2000 V G5, the first discrete silicon carbide diode on the market with a breakdown voltage of 2000 V. The product family is suitable for applications with DC link voltages up to 1500 VDC and offers current ratings from 10 to 80 A. This makes it ideal for higher DC link voltage applications such as in solar and EV charging applications.

The product family comes in a TO-247PLUS-4-HCC package, with 14 mm creepage and 5.4 mm clearance distance. This, together with a current rating of up to 80 A, enables a significantly higher power density. It allows developers to achieve higher power levels in their applications with only half the component count of 1200 V solutions. This simplifies the overall design and enables a smooth transition from multi-level topologies to 2-level topologies.

In addition, the CoolSiC Schottky diode 2000V G5 utilizes the .XT interconnection technology that leads to significantly lower thermal resistance and impedance, enabling better heat management.   Furthermore, the robustness against humidity has been demonstrated in HV-H3TRB reliability tests. The diodes exhibit neither reverse recovery current nor forward recovery and feature a low forward voltage, ensuring enhanced system performance.

The 2000 V diode family is a perfect match for the CoolSiC MOSFETs 2000 V in the TO-247Plus-4 HCC package that Infineon introduced in spring 2024. The CoolSiC diodes 2000 V portfolio will be extended by offering them in the TO-247-2 package, which will be available in December 2024. A matching gate driver portfolio is also available for the CoolSiC MOSFETs 2000 V.

The RISC-V-based MPUs support mission-critical intelligent edge applications with TSN Ethernet switching and AI capabilities

The global edge computing market is expected to grow by more than 30 percent in the next five years, serving mission-critical applications in the aerospace, defense, military, industrial and medical sectors. To meet this increasing demand for reliable, embedded solutions for mixed-criticality systems, Microchip Technology has announced the PIC64HX family of microprocessors (MPUs). Unlike traditional MPUs, the PIC64HX is purpose-built to address the unique demands of intelligent edge designs.

The latest in Microchip’s 64-bit portfolio, the PIC64HX is a high-performance, multicore 64-bit RISC-V MPU capable of advanced Artificial Intelligence and Machine Learning (AI/ML) processing and designed with integrated Time-Sensitive Networking (TSN) Ethernet connectivity and post-quantum-enabled, defense-grade security.

PIC64HX MPUs are specifically designed to deliver comprehensive fault tolerance, resiliency, scalability and power efficiency.

“The PIC64HX MPU is truly groundbreaking in the number of advanced features we are able to provide with a single solution,” said Maher Fahmi, corporate vice president of Microchip’s communications business unit. “And, integrating TSN Ethernet switching into the MPU helps developers bring standards-based networking connectivity and compute together to simplify system designs, reduce system costs and accelerate time to market.”

The integrated Ethernet switch includes a TSN feature set with support for important emerging standards: IEEE P802.1DP TSN for Aerospace Onboard Ethernet Communications, IEEE P802.1DG TSN Profile for Automotive In-Vehicle Ethernet Communications and IEEE/IEC 60802 TSN Profile for Industrial Automation.

Eight 64-bit RISC-V CPU cores—SiFive Intelligence X280—with vector extensions help enable

high-performance compute for mixed-criticality systems, virtualization and vector processing to accelerate AI workloads. The PIC64HX MPU allows system developers to deploy the cores in multiple ways to enable SMP, AMP or dual-core lockstep operations. WorldGuard hardware architecture support is provided to enable hardware-based isolation and partitioning.

“Next-generation aircraft require a new generation of processors for mission-critical applications such as flight control, cockpit display, cabin networking and engine control. The OHPERA Consortium views RISC-V technology as an essential component of the future of safe and sustainable aircraft,” said Christophe Vlacich, OHPERA technical Leader. The OHPERA Consortium is composed of leading aerospace companies with the mutual goal of evaluating new technologies for next-generation aircraft.  “We are pleased to see the upcoming availability of commercial products like Microchip’s PIC64HX MPU with the compute performance, partitioning, connectivity and security needed to shape the future of aviation.”

The expected arrival of quantum computers poses an existential threat as it will make current security measures ineffective. As a result, government agencies and enterprises worldwide are beginning to call for the inclusion of post-quantum cryptography in any critical infrastructure. Addressing current and future security needs, the PIC64HX is one of the first MPUs on the market to support comprehensive defense-grade security including the recently NIST-standardized FIPS 203 (ML-KEM) and FIPS 204 (ML-DSA) post-quantum cryptographic algorithms.

The PIC64HX MPU is a powerful and versatile solution for intelligent edge applications, addressing key requirements for low latency, security, reliability and compliance with industry standards.

Using the most advanced GaN manufacturing technology available today, Aizu, Japan, is now the company’s second factory to produce a complete portfolio of GaN-based power semiconductors

NEWS HIGHLIGHTS:

• TI adds GaN manufacturing in Japan, quadrupling its internal GaN manufacturing capacity between its factories in the United States and Japan.
• TI’s GaN-based semiconductors are in production and available now.
• TI enables the most energy-efficient, reliable and power-dense end products with the widest portfolio of integrated GaN-based power semiconductors.
• TI has successfully piloted the development of GaN manufacturing on 300mm wafers.

Texas Instruments has announced it has begun production of gallium nitride (GaN)-based power semiconductors at its factory in Aizu, Japan. Coupled with its existing GaN manufacturing in Dallas, Texas, TI will now internally manufacture four times more GaN-based power semiconductors, as Aizu ramps to production.

“Building on more than a decade of expertise in GaN chip design and manufacturing, we have successfully qualified our 200mm GaN technology – the most scalable and cost-competitive way to manufacture GaN today – to start mass production in Aizu,” said Mohammad Yunus, TI’s senior vice president of Technology and Manufacturing. “This milestone enables us to manufacture more of our GaN chips internally as we grow our internal manufacturing to more than 95% by 2030, while also sourcing from multiple TI locations, ensuring a reliable supply of our entire GaN portfolio of high-power, energy-efficient semiconductors.”

The power of GaN technology

An alternative to silicon, GaN is a semiconductor material that offers benefits in energy-efficiency, switching speed, power solution size and weight, overall system cost, and performance under high temperatures and high-voltage conditions. GaN chips provide more power density, or power in smaller spaces, enabling applications such as power adapters for laptops and mobile phones, or smaller, more energy-efficient motors for heating and air conditioning systems and home appliances.

Today, TI offers the widest portfolio of integrated GaN-based power semiconductors, ranging from low- to high-voltage, to enable the most energy-efficient, reliable and power-dense electronics.

“With GaN, TI can deliver more power, more efficiently in a compact space, which is the primary market need driving innovation for many of our customers,” said Kannan Soundarapandian, vice president of High-Voltage Power at TI. “As designers of systems such as server power, solar energy generation and AC/DC adapters face challenges to reduce power consumption and enhance energy efficiency, they are increasingly demanding a reliable supply of TI’s high-performance GaN-based chips. TI’s product portfolio of integrated GaN power stages enables customers to achieve higher power density, improved ease of use and lower system cost.”

Further, with the company’s proprietary GaN-on-silicon process, more than 80 million hours of reliability testing, and integrated protection features, TI GaN chips are designed to keep high-voltage systems safe.

Most advanced GaN manufacturing technology available today

Using the most advanced equipment available for GaN chip manufacturing today, TI’s new capacity enables increased product performance and manufacturing process efficiency, as well as a cost advantage.

Also, the more advanced, efficient tools used in TI’s expanded GaN manufacturing can produce smaller chips, packing even more power. This design innovation can be manufactured using less water, energy and raw materials, and end products that use GaN chips enjoy these same environmental benefits.

Scaled for future advances

The performance benefits of TI’s added GaN manufacturing also enable the company to scale its GaN chips to higher voltages, starting with 900V and increasing to higher voltages over time, furthering power-efficiency and size innovations for applications like robotics, renewable energy and server power supplies.

In addition, TI’s expanded investment includes a successful pilot earlier this year for development of GaN manufacturing processes on 300mm wafers. Further, TI’s expanded GaN manufacturing processes are fully transferable to 300mm technology, positioning the company to readily scale to customer needs and move to 300mm in the future.

Committed to responsible, sustainable manufacturing

Expanding supply and innovation in GaN technology is the latest example of TI’s commitment to responsible, sustainable manufacturing. TI has committed to use 100% renewable electricity in its U.S. operations by 2027, and worldwide by 2030.

Delivers SMT and IP67 for high-efficiency performance in automotive, consumer, medical, and industrial applications

Littelfuse, Inc., an industrial technology manufacturing company empowering a sustainable, connected, and safer world, announces the C&K Switches KSC DCT Series Tactile Switches. The KSC DCT (Dual Circuit Technology) series are sealed IP67-rated, momentary-action tactile switches for surface-mount technology (SMT), designed to give users a positive, adaptable tactile feeling.

The KSC DCT is the first tactile switch to offer single pole double throw (SPDT) functionality in a small 6.2 x 6.2 x 5.2 millimeters size. The switches feature a soft actuator that withstands an operating force of 4.75N (+/-1.25N) and has a lifespan of 300K life cycles. The KSC DCT Series is a logical choice for seamless integration into existing or next-generation designs, providing outstanding, long-term reliability in even the dustiest environments.

The KSC DCT Tactile Switches offer these key features and benefits:

• SPDT Functionality: Added reliability due to one input and two outputs in a single tactile switch.
• Compact Footprint: Fits applications where space is limited.
• IP67 Sealing: Provides high contact reliability, protecting against dust and water ingress.
• J-Bend SMT Package: Enables standard assembly mounting using typical pick-and-place machines. (Gullwing-type terminations are also available.)
• Cost-Efficient: SMT makes it ideal for high-volume applications.

The KSC DCT Series Tactile Switches are ideally suited for:

• Transportation: Automotive door handles, EV charging station units, two- and three-wheelers.
• Consumer Electronics: Power tools, lawn mowers, snow blowers, home appliances.
• Medical Devices: Electrosurgical instruments, portable medical devices.
• Industrial Applications: Elevators, fire alarm equipment.

“By designing the unique functionality of dual-circuit technology tactile switches into such a small form factor, Littelfuse engineers are enabling electronics designers to provide their end-customers a journey to a safer world,” said Jeremy Hebras, Vice President of Digital & Technical Developments, Electronics Business Unit Engineering, at Littelfuse. “Thanks to the KSC DCT’s patented design, everyone can now precisely monitor the actual status of an electromechanical surface-mount technology tactile switch, even when the switch is not in use, which helps discriminate a silent signal versus a device malfunction.”

The increased safety needs of today’s end users require active failure verification: with the added single pole double throw (SPDT) functionality, the KSC DCT tactile switch allows a system to actively verify failures, like an unwanted door opening.

How it works: Dual-Circuit Technology (DCT) is a feature that creates two independent output signals inside the body of one tactile switch–Single Pole Double Throw (SPDT). The KSC DCT tactile switch has a Common, Normally Close (NC), and Normally Open (NO) pin. Suppose the designer chooses to use both NC and NO circuitry. In that case, it provides a Changeover signal that allows the designer to use both circuitries to define the logic of the signal and take actions based on the defined logic. In an automotive door handle, for example, both NC and NO circuitries are used before making any decision. The logic is at rest; the NC contact is closed while the NO contact is open. When a user pushes the button, nothing will happen until the NC contact is open and the NO contact is closed.

Spectrum Instrumentation launches flagship series of AWG cards in PCIe format

Scientists and engineers now have a way to produce high-frequency arbitrary waveforms, with high purity and low distortion, directly from their PC. Using the new PCIe flagship AWG cards from Spectrum Instrumentation and cost-effective COTS (Commercial-of-the-shelf) PC-parts, it is possible to generate nearly any waveform with up to 10 GS/s output rates, 2.5 GHz bandwidth, and 16-bit vertical resolution. The new cards make a powerful alternative to benchtop AWGs that often face a bottleneck when loading data for new waveforms. The cards offer a massive onboard memory of up to 8 GigaSamples (16 GB) and the possibility to stream data at up to 10 GigaBytes per second directly from CPUs or even GPUs. Four different models make up the M5i.63xx AWG series, offering a perfect fit solution for every application.

Insert the cards into a suitable PC and it turns into one of the most powerful signal generation instruments on the market. The four AWG variants deliver waveform generation with bandwidths of 2.5 and 1.5 Gigahertz (GHz) and output rates of 10, 5 or 3.2 Gigasamples per second (GS/s). The units combine 16-bit vertical resolution with programmable full-scale outputs. Single outputs deliver up to ±500 mV into 50 Ohm and ±1.0 V into high impedance loads – or double the range in differential mode.

Ultrafast data streaming

Each card comes with 2 GSample of onboard memory (8 GSample optional) and high-speed data transfer using a 16 lane, Gen 3, PCIe bus. This ultrafast bus allows data to be sent to cards at a staggering 10 GB/s. For demanding applications, data can even be continuously streamed directly to the AWG for replay in a FIFO mode – a process that allows almost limitless waveform production. Add Spectrum’s SCAPP driver package, which allows FIFO streaming directly to and from a GPU, and turbocharge the waveform processing even further.

The four new AWG flagships in PCIe format combine up to 10 GS/s speed, up to 2.5 GHz bandwidth, and 16-bit resolution. In the diagram, a two-channel M5i.6357 generates the two signals (I and Q component) for a Quadrature-Modulation.

Versatile Waveform Generation

Waveforms can be output in Single-shot, Repeated and Multiple Replay modes. To maximize memory efficiency, Multiple Replay can be used to output segmented data and can also be combined with FIFO streaming. Waveform replay can be initiated by a simple software command or via a trigger event. Trigger signals can be input on two external trigger lines.

Multi-channel Systems

Individual cards have one or two analog output channels. To create larger multi-channel systems, cards can be connected together using the company’s proprietary Star-Hub clock and trigger synchronization module. Star-Hub allows systems with up to eight cards to share a common clock and trigger, delivering fully synchronous output rates of 5 GS/s on up to 16 channels, or 10 GS/s on up to eight channels.

Mixed AWG and Digitizer Systems

The new flagship AWGs are available with one or two output channels, which can be used single-ended or differential (see front panel on the right).

The four new models of the M5i.63xx AWG series and the seven variants of the M5i.33xx digitizer series are designed for working together, making them ideal for use in stimulus-response, receiver-transmitter or closed-loop type testing systems. For example, if two Star-Hubs are used, ultrafast MIMO systems can be built that contain up to 8 AWGs and 8 digitizers. This allows the creation of systems with up to 16 transmit and 16 receiver channels, each channel with 5 GS/s.

Easy connection with other devices

For easy system integration, the front-panel hosts four multi-function SMA connectors. These can perform a variety of Input/Output tasks like Asynchronous Digital-I/O, Synchronous Digital-Out, Trigger Output, Run and Arm status flags, or the System Clock. By switching the multi-function I/O lines to digital outputs, another four synchronous output channels can be added to the AWG. As such, a single AWG card can generate up to two analog and four digital outputs, in parallel, at full speed. As an option, a Digital Pulse Generator firmware is available to turn the four digital outputs into digital generators outputs. All these features are very helpful when interfacing with other equipment for experiment control or in OEM projects.

Fully programmable

Fully programmable, the cards run under Windows or LINUX operating systems, using today’s most popular and powerful software languages. All products are shipped together with SDKs for C++, C#, Python, VB.NET, Julia, Java and IVI. Drivers are also provided for third-party software products LabVIEW and MATLAB.

Five Year Warranty

The Spectrum M5i.63xx series AWGs are available for immediate delivery. All cards are shipped factory tested and include a five-year warranty, with software and firmware updates, free of charge, for the lifetime of the product.

New best-of-both memory combines serial Flash speed and density with EEPROM byte-level flexibility

STMicroelectronics’ Page EEPROM combines the power efficiency and durability of an EEPROM with the capacity and speed of a Flash memory, creating a hybrid memory for applications that face extreme size and power constraints.

The new memories address growing demand for storage in embedded applications, needed to support increasingly sophisticated features and run data-hungry edge-AI algorithms. One example is behind-the-ear hearing aids, where Page EEPROM can reduce the bill of materials and help create products that are slimmer and more comfortable to wear.

In addition to wearables, Page EEPROM is ideal for applications such as healthcare devices, asset trackers, e-bikes, as well as other industrial and consumer products. “The intelligent edge has evolved quickly and is profoundly changing demands on embedded memory storage density, performance, and power consumption,” said Philippe Ganivet, STMicroelectronics EEPROM product line manager.  “Our new Page EEPROM is the perfect ultra-low-power memory to complement a microcontroller for remote IoT modules that operate on battery power.”

“ST’s Page EEPROM is the perfect non-volatile memory, a true best-of-both worlds solution that enabled us to achieve the ambitious targets we set when creating the latest generation of our flagship product family of GPS trackers, IoT devices, and all other designs where high performance, high reliability, small size, and low power are required,” said Patrick Kusbel, owner of BitFlip Engineering, one of the first customers to use the new memory ICs. “The M95P is up to 50 times faster yet consumes as little as one-tenth the power and delivers five times the reliability — at 500k writes compared to 100k writes — typical of other parts we used before. It’s a game changer.”

ST’s Page EEPROM family offers densities of 8Mbit, 16Mbit, and 32Mbit, greatly increasing storage over standard EEPROM devices. Embedded smart page-management allows byte-level write operations for processes like data logging, while also supporting page/sector/block erase and page-program up to 512 bytes for efficiently handling firmware over the air (OTA) updates. The devices also allow buffer loading, which can program several pages simultaneously to cut the time for loading software in production. The data-read speed of 320 Mbit/s is about 16 times faster than standard EEPROM, while write-cycle endurance of 500,000 cycles is several times higher than conventional serial Flash.

Also featuring a novel peak-current control, Page EEPROM minimizes power supply noise and prolongs the runtime of battery-operated equipment. The write current is below that of many conventional EEPROMs and there is also a deep power-down mode with fast wakeup that reduces the current to below 1µA.

Longevity is assured, with 100-year data retention. The devices are included in ST’s 10-years product longevity program that guarantees long-term product availability.

The X-NUCLEO-PGEEZ1 expansion board and X-CUBE-EEPRMA1 software package are available now, for users to learn how to interact with Page EEPROM and adopt the new devices in application designs. The software includes a demonstration application that shows how to test the memory’s hybrid architecture and quickly build a proof of concept.

In today’s tech-driven era, automotive electronics have become integral to modern vehicles, comprising an array of systems such as engine management, ignition, radio, carputers, telematics, in-car entertainment systems, among others. Over time, the importance of these electronic systems has been growing. Historically, electronics constituted about 10% of the total car cost till the 1980s, later, this share reached 35% by 2010, according to Statista. Keeping pace with the trend, in 2030, electronics are projected to make up around 50% of the cost of a new car. The main drivers of this rise are attributed to electronics usage in cars and the broader trends of connectivity and automation.

Considering this upsurge, technology is destined to lead the way for the automotive electronics sector in the foreseeable future. To speed fast its systems, telematics and the Internet of Things (IoT) can create welcome opportunities. Telematics, in particular, is capable of tracking the vehicle to transmit and store real-time data about its location, operation, and function. Subsequently, this data can be used to improve driver safety, increase efficiency, and reduce costs. Similarly, automotive IoT forms an essential component of connected car technology allowing vehicles to interact with external objects and road users such as other vehicles, people, or road infrastructure, and ensure greater road safety and traffic efficiency.

Let’s look at how telematics and IoT are evolving to aid automotive electronics:

Additionally, IoT apps ease fleet management with the help of integrated weight management, location tracking and advanced sensors.
• Data Collection and Analysis: Tracking devices powered by telematics collect and transmit data, such as GPS position, speed, and fuel consumption. The data is sent to a centralised server, where it can be analysed and optimised for user interfaces. Moreover, the increase in electronics has enhanced vehicles’ capabilities to monitor both internal and external conditions. Thus, connected cars are capable of sharing these kinds of information with other devices via a robust IoT ecosystem. Interestingly, it is projected that by 2025, there will be over 400 million connected cars in operation, up from some 237 million in 2021.
• Live Monitoring and Safety Enhancement: Telematics allows for real-time monitoring of vehicles, especially in semi-autonomous cars. It is put in place with GPS and onboard diagnostics to record and map the vehicle’s location, route, speed, and ensure the safety of people. Moreover, IoT-infused semi-autonomous cars make on-spot decisions while partly controlling the vehicle operations to avoid accidents and reduce the load from the driver. Along with different proximity sensors and cameras, cars are integrated with IoT systems to reduce human error and make driving more comfortable and safe.
• Predictive Analysis and Improved Efficiency: A sought-after feature of automotive electronics is predictive analytics. Telematics data helps businesses make insightful decisions to identify potential issues. These systems can proactively alert drivers if they swerve, and detect drowsiness using vision AI models. As for IoT, it aids in taking necessary actions to prevent car parts from sudden breakdowns.

Future Prospects

Looking ahead, as the field of telematics matures, smart cars will continue tapping into IoT sensors and devices that link vehicles in cities via smart traffic technologies. Automotive manufacturers will use telematics for a variety of testing and training purposes such as gaining deeper insights into onsite or remote testing, creating predictive models for vehicle integrity, training employees virtually, as well as running simulations to improve crash-test safety.

The sector is bound to integrate AI to analyse large amounts of data from vehicle sensors for autonomous driving capabilities. Future vehicles may even influence telematics to provide tailored experiences based on driver preferences and habits, including navigation, entertainment, and comfort settings. With the rise of electric vehicles, telematics will play a major role in managing battery health, optimising charging, and planning energy-efficient routes. Ultimately, these developments will certainly shape business opportunities and process refinements in automotive electronics that were previously unattainable.

X-CUBE-STL now supports the STM32MP1, the STM32U5, the STM32L5, the STM32H5, and the STM32WL. In essence, the most extensive family of general-purpose microcontrollers capable of running Safety Integrity Level 2 and 3 certified systems continues to grow, and teams needing to meet IEC 61508, ISO 13849, and IEC 61800 requirements can do so on our latest devices. Additionally, the Functional Safety page will make finding the various ST resources that will assist developers striving for industrial or household electrical appliance certifications easier. It also lists the ST Authorized Partners providing real-time operating systems, development tools, engineering services, and training to ensure teams can cross the bridge from proof-of-concept to commercial products.

• Watch our Webinar on functional safety

The International Electrotechnical Commission defines safety as the “freedom from unacceptable risk of physical injury or of damage to people’s health.” When designing an embedded system, functional safety covers the various aspects of safety that depend on that system. For instance, in a manufacturing plant, functional safety ensures that in case of an internal failure, the circuit controlling a robot fails gracefully instead of harming its operators. In a medical application, standards guarantee that users are aware of malfunctions by the use of an alarm, among other things, to prevent detrimental usage. And since our STM32 microcontrollers are everywhere, we needed to see that they all had a straightforward path to IEC 61508 for industrial applications.

Before X-CUBE-STL: How to start working on an IEC 61508 certification A robot arm in an industrial setting

The IEC 61508 governs functional safety for electrical and electronic systems in all sorts of industries and applications. However, many STM32 users seek this certification when working in an industrial setting where risks are higher and requirements more stringent. The first significant aspect of the standard is the safety life cycle. Before anything else, engineers must document all the steps and measures they will take to accomplish functional safety, from the first design operations to the product’s decommissioning. The process includes risk analysis, safety protocols, and validations, maintenance, etc.

Our Functional Safety page is a great starting point for engineers because it provides a “safety manual” for nearly all STM32 microcontrollers, thus ensuring that teams can begin working on defining their product’s life cycle. Most documentation focuses on IEC 61508 compliance. However, we recently published an application note (AN5698) to help engineers adapt what’s in the X-CUBE-STL package to other safety certifications, such as ISO 13849, for safety of machinery. We also provide a failure mode and effect analysis (FMEA), which lists all the MCU failure modes and how to mitigate them. Similarly, the failure mode effect and diagnostic analysis (FMEDA) extends the former and computes failure rates for the MCU at the function level.

X-CUBE-STL: Self-test libraries to more rapidly obtain SIL 2 or SIL 3 certifications Understanding Safety Integrity Levels

The second aspect of IEC 61508 is the assignment of a Safety Integrity Level (SIL). After a hazard analysis determines what can go wrong and how badly it can damage a person or the environment, there’s a risk assessment to determine how often or how likely a hazard can occur. From these analyses, functional safety standards draw safety requirements or SIL.

There are four levels, the first being the laxest and the fourth representing the strictest standard. SIL 4 is traditionally for railway or nuclear applications. SIL 1 is looser and tends to apply to monitoring/information devices like CCTV, while SIL 2 and 3 are much more common in hardware designed for industrial applications. The main difference is the requirement to perform redundant measurements in SIL 3.

Knowing how to get started

To start working toward SIL 2 or SIL 3 certifications, teams begin by selecting an STM32 with the hardware safety features that match their application’s requirement. For instance, all our MCUs have a dual watchdog, but only the STM32G0, STM32G4, STM32H5, STM32H7, STM32L4/L4+, STM32L5, STM32U5, STM32WB/A, and STM32WL have ECC Flash memory, and out of them, only the STM32H7, STM32H5, and STM32U5 have ECC SRAM, which is traditionally only a requirement for high-performance applications.

Teams can also use the self-test libraries available in the X-CUBE-STL to start implementing failure detection mechanisms. For instance, they can help spot random failures in the CPU, the SRAM, or the Flash. The diagnostic capability of X-CUBE-STL is verified by fault injection methodology to improve the customers’ confidence in our solutions. To make these libraries more accessible, we offer them as object code, meaning that they can be integrated into any application, and developers can use any compiler.

X-CUBE-STL provides object code to help developers run self-tests on STM32 MCUs. Consequently, because we deliver an object code, developers can integrate it into their software, certify one object, and reuse it multiple times since it doesn’t depend on the compiler version or other dependencies. It greatly facilitates the process when applying to certification bodies.

X-CUBE-CLASSB and why an ecosystem matters Sharing resources

Recently, ST updated its X-CUBE-CLASSB, which targets electrical household appliances, to align it with X-CUBE-STL. Put simply, while they have different user manuals and different purposes, the selt-test libraries share the same code base with X-CUBE-STL. Hence, it becomes much easier to obtain more than one certification on the same hardware platform. Additionally, since these certifications are much less stringent than IEC 61508, the ability to use the same object code as the X-CUBE-STL provides greater assurance. The software package currently supports the STM32U5, STM32G0, STM32C0, STM32L4, STM32G4, STM32WL, STM32MP1, STM32H5, STM32F7, and STM32H7. Support for the STM32H7R/S, STM32U0, and STM32F4 will arrive by the end of the year.

Optimizing functional safety

All these packages turn our STM32 general-purpose microcontrollers into great candidates for the most complex protocols. Traditionally, MCUs aimed at these standards are custom products, which means that they are much more expensive and use hardware specifications that are sometimes more prohibitive in one way or another. ST’s approach is thus unique because we make these standards more accessible and provide an essential network of partners. In many instances, using two STM32s is still more cost-effective than using one MCU sold specifically for safety.

As great as the documentation and self-test libraries are, we know that they represent only the first steps in a long process. Many teams often underestimate the difficulties associated with getting a certification. Hence, we also have ST Authorized Partners who know our devices and can ensure engineers cross the finish line by shipping a certified product.

The post Press release of Keysight Technologies, Inc. about how it is propelling Pegatron 5G to transform power efficiency for open radio access network (RAN) appeared first on ELE Times.

GÖPEL electronic introduces the new Multi Line product family, an innovative platform of inspection systems that supports the entire manufacturing process. The centerpiece of this solution is a modular base system with a uniform and powerful software interface. This reduces training requirements, enables flexible employee scheduling, and optimizes the exchange of knowledge between production staff. This can be especially important when there may be a shortage of skilled workers.

The all-rounder can be configured for all inspection tasks throughout the entire manufacturing process: for solder paste inspection (SPI), for surface mount technology (SMT) and through-hole technology (THT) automated optical inspection (AOI), and also for conformal coat inspection (CCI). For THT printed circuit board assemblies (PCBA), Multi Line provides flexible transport options, with or without carriers, and all the necessary camera modules for this application. It also allows THT solder inspection, even during return on the optional lower transport conveyor. Thanks to 3D technology, solder joints can be inspected not only for soldering quality and for shorts, but also for solder volume and pin length, without flipping the PCBA.

The system’s configuration versatility also makes it suitable for use in the SMT process, where optional double-sided inspection offers the advantage of fully testing SMT assemblies without flipping the PCBA.

Furthermore, Multi Line is available as an SPI system for the inspection of solder paste deposits in regard to shape, height, area, bridges, volume, X/Y offset, and co-planarity. A closed-loop interface to the solder paste printer is available, and a link to PILOT Verify software makes fault analysis more efficient by displaying associated AOI, AXI, and SPI result data.

Multi Line CCI can automatically inspect protective coatings by making fluorescent coatings glow using UV LEDs of different wavelengths. With telecentric optics and a color camera, the system delivers high-contrast images and enables fast programming using CAD data and coating plans. As a special feature, the PCBA can be simultaneously inspect both top and bottom without turning, and, if necessary, can also be transported back to the beginning of the line using a lower level return conveyor.

Thanks to the modular design of the Multi Line platform, camera modules can be flexibly combined and, if necessary, retrofitted later for new applications in the manufacturing process.

With this comprehensive solution, GÖPEL electronic is utilizing its many years of experience in quality assurance and setting new standards in inspection technology for the electronics manufacturing process.

GÖPEL electronic develops and manufactures innovative electrical and optical test, measurement, and inspection equipment for electronic components and printed circuit board assemblies as well as industrial and automotive electronics systems. GÖPEL electronic is comprised of four business units:

Microchip’s RTG4 FPGAs with Lead-Free Flip-Chip Bumps Achieve Highest Space Qualification

QML Class V designation recognizes exceptional reliability and longevity for critical space missions

 

October 18, 2024 — Satisfying mission assurance requirements for the most critical space programs, Microchip Technology’s (Nasdaq: MCHP) Radiation-Tolerant (RT) RTG4 Field- Programmable Gate Arrays (FPGAs) with lead-free flip-chip bumps have earned the Qualified Manufacturers List (QML) Class V status. As designated by the Defense Logistics Agency (DLA), QML Class V is the highest level of qualification for space components and a necessary step to satisfy mission assurance requirements on the most critical space missions such as human-rated, deep space and national security programs. Because QML qualifications are standardized based on specific performance and quality requirements governed by the DLA, customers can streamline their design and certification processes by using QML-qualified products.

 

In 2018, RTG4 FPGAs became the first RT FPGAs offering more than 150,000 logic elements to achieve a QML Class V qualification, and this next-generation solution with lead-free flip-chip bumps is the first of its kind to achieve QML Class V status. In advanced flip-chip package construction, such as that used in the RTG4 FPGA, flip-chip bumps are utilized to connect the silicon die and the package substrate. Lead-free bump material will help extend the longevity of the product, which is critical to space missions.

 

“This is another milestone for our RTG4 FPGAs that will provide customers with added confidence in designing these devices in space flight systems, while allowing them to take advantage of our high-reliability, zero-configuration-upset and low-power consumption FPGAs,” said Bruce Weyer, corporate vice president for Microchip’s FPGA business unit. “For more than 60 years, Microchip solutions have powered space flight missions, and we are dedicated to product longevity and providing the highest quality solutions.”

 

RTG4 FPGAs are designed to bring high levels of density and performance to space applications, saving cost and engineering efforts through low power consumption and immunity to configuration upsets. Unlike SRAM-based FPGA alternatives, the programming technology used in RTG4 FPGAs provides low static power, which assists in managing thermal issues common in spacecraft. RTG4 FPGAs consume only a fraction of the total power compared to equivalent SRAM FPGAs, while exhibiting zero configuration upsets in radiation and thus requiring no mitigation, reducing engineering expenses and total system costs.

 

To achieve QML Class V qualification, the RTG4 FPGA with lead-free bump has undergone extensive reliability testing, enduring up to 2,000 thermal cycles from −65°C to 150°C junction temperature. The lead-free flip-chip bump interface connections passed MIL-PRF-38535 inspection criteria and exhibited no signs of tin whiskers. The flip-chip bump is inside the FPGA package, so there is no impact on the user’s design, reflow profile, thermal management or board assembly flow when converting to lead-free bump RTG4 FPGAs.

 

Microchip boasts one of the industry’s most comprehensive space product portfolios of radiation-hardened and RT solutions that include QML Class Q RT PolarFire® FPGAs and sub-QML FPGAs that bridge the gap between traditional Qualified Manufacturers List (QML) components and Commercial Off-The-Shelf (COTS) components. For a comprehensive listing of Microchip FPGA and mixed-signal part numbers alongside their corresponding Defense Logistics Agency (DLA) drawing numbers, please refer to the DLA Cross Reference Guide.

 

Development Tools

The RTG4 FPGAs are supported by development kits, mechanical samples and daisy chain packages for board validation and testing. Libero® SoC Design Suite enables RTL entry through programming and includes a rich IP library, complete reference designs and development kits.
