In a world of increasing connectivity and the growing popularity of the Internet of Things, it is important to simplify interoperability across connected devices and to enhance their security and reliability. The Matter standard was created precisely for this purpose. In order to facilitate integration of the Matter standard and security features into smart home and smart building devices, Infineon Technologies now introduces the OPTIGA Trust M MTR. The Matter-certified Secure Element is the latest configuration of Infineon’s OPTIGA Trust M, combined with a Matter provisioning service.

Matter: smooth interoperability of connected devices

According to ABI Research forecasts, the number of smart home devices will double by 2030, reaching about 1.7 billion worldwide. All these devices have to be able to connect securely and reliably with each other and with different smart home ecosystems. That’s where the Matter standard comes into play, facilitating smooth interoperability across connected devices even from different companies. The Matter protocol defines a set of principles that support uniform security and privacy measures for the smart home, since smart homes rely on smart devices to increase not only comfort but also efficiency and security.

“When we designed the Matter protocol in the Connectivity Standards Alliance, we were committed to building strong security,” said Steve Hanna, Distinguished Engineer at Infineon and leader of the standards teams that defined Matter’s security. “That’s why Matter brings new security features to the smart home, some of which were challenging for IoT product designers. Infineon’s OPTIGA Trust M MTR addresses those challenges head-on so that now it can be even easier to build a Matter product.”

OPTIGA Trust M MTR facilitates Matter and security integration

The tamper-resistant security controller can be easily integrated into a system to perform security-related functions and provide a high level of protection for sensitive data and cryptographic operations. As a discrete Secure Element, OPTIGA Trust M MTR can be integrated into any MCU-based design to enhance security and handle multiple product protocols simultaneously. This gives original equipment manufacturers greater flexibility and allows faster time to market.

According to the Matter protocol, every smart home device must have a Device Attestation Certificate (DAC), containing the Product ID (PID) and the Vendor ID (VID), to verify the authenticity and trustworthiness of each device commissioned in the Matter ecosystem. With OPTIGA Trust M MTR, the PID no longer needs to be defined in advance when the reel is ordered or manufactured. Instead, each device receives a personalized DAC injection at a later point right up until the start of device production. This gives device manufacturers more flexibility in creating multiple product variants of smart home devices.

OPTIGA Trust M MTR Secure Elements are pre-provisioned at a Common Criteria-certified Infineon facility. The batch of Secure Elements on a reel is shipped with an associated barcode. The customer claims ownership of these chips on the IoT portal of Infineon partner Kudelski IoT by scanning the barcode. Kudelski IoT is a trusted and established Product Attestation Authority (PAA) approved by the Connectivity Standards Alliance (CSA). Kudelski IoT will enable the download of production DACs corresponding to the vendor and the product. Finally, the personalized DAC is transferred to the OPTIGA Trust M MTR at the factory level (see graphic).

Please note: An Online Media Briefing will be held on 22 February 2024 (3:00 pm CET / 9:00 am EST), in which Distinguished Engineer Steve Hanna will present additional information about the new OPTIGA Trust M MTR.

About Matter: In order to enhance the security and reliability of smart devices, Infineon and more than 600 companies are collaborating in the Connectivity Standards Alliance (CSA) to simplify and harmonize the Internet of Things using technology standards such as Matter. Matter was created to keep devices and information protected and private, yet easy to use. The Matter standard provides guidance to device manufacturers, enabling them to select the appropriate platform security for their devices and corresponding use cases. Matter embeds privacy principles into all interactions between devices and software agents that handle personal data. Ultimately, it creates the foundation for connected things by supporting simplicity, interoperability, reliability and security.

eDSim is our latest simulation tool for switched-mode power supplies (SMPS) and other power analog circuits. The tool runs on the SIMPLIS/SIMetrix engine, is available to download for free on our website, and is governed by a free-to-use commercial license. In a nutshell, our eDSim models are exempt from node limit count, thus enabling engineers to utilize them without restrictions on the number of nodes or circuit size. We even worked on a workflow that allows users to export a design out of eDesignSuite and into eDSim to help them run more detailed simulations faster. ST is also working on an online version of eDSim to optimize further the experience of designing and simulating a circuit.

Why did we decide to work on this? The challenges behind designing power circuits

Power circuits are notoriously difficult to design because of their inherent complexity. Engineers must account for a specific load and how the overall circuit responds when there are sudden shifts in the line voltage or the load current due to spikes or low loads. In the case of an SMPS, teams must ensure that cycles are consistent, meaning that no significant fluctuations disrupt voltage regulations. It’s also critical to examine how the circuit performs under regular operations to determine the overall quality of the design. Is the ramp-up, when the input voltage is first applied, smooth, or is there a massive under- or over-shoot, among other issues?

The necessity of running simulations A simulation in eDSim

Until simulations came along, the only way for engineers to test their power circuit was to design a PCB layout, manufacture it, and then physically try it in their lab. The obvious problem is that the process is slow and extremely expensive. Furthermore, because power calculations are often based on differential equations, complex models, and matrix computations1, teams may spot a problem but may not have an obvious solution to it, requiring even costlier trial-and-error operations. Hence, simulators are an essential tool when designing a power circuit. Unfortunately, licenses can be expensive, and knowing what software to use isn’t always obvious. Consequently, we tackled this problem so our partners wouldn’t have to.

Why did we invest so much time and money into eDSim? 10x to 50x faster

In essence, eDSim takes the SIMPLIS/SIMetrix engine and runs it on ST components and models. Why choose this engine? According to our benchmarks, simulating a synchronous step-down converter based on our L6983 would take between 10 minutes and 50 minutes on OrCAD PSpice, but only one minute or less on eDSim, thanks to its SIMPLIS/SIMetrix implementation. OrCAD PSpice takes a general-purpose approach to circuit simulation, which explains why it is very popular in many other instances. On the other hand, SIMPLIS/SIMetrix specializes in the types of calculations that are essential when simulating a power stage, which is why it can be 10 to 50 times faster at modeling a switching circuit.

A useful license for the ST community

ST worked with SIMPLIS Technologies to ensure we could provide professional engineers with one of the most flexible licenses. For instance, working with one of our models doesn’t contribute to the eDSim node count or circuit size limit, regardless of its complexity. A brief overview eDSim will reveal that we have tens of models for SMPS and analog ICs. We are also in the process of extending the coverage with power discrete and other smart power devices in future releases.

How to get started?

eDSim is a testament to our desire to create more accessible solutions and bridge digital divides. By working with SIMPLIS Technologies to offer our utility for free, any engineer can build a power circuit and learn from one of the most powerful simulators in the industry. All it takes is to download eDSim from ST.com. Additionally, to increase accessibility even further, we are happy to announce that we are working on an online version of eDSim and will update this blog post when it becomes available. In the meantime, we published the videos below to show how to get started, and we are also offering an example application built on the L6983.

What’s new? NeoChromVG GPU! The challenge of creating UIs with less memory

The reason ST decided to release a specific hardware IP accelerating vector operations is because it was an increasingly popular demand from customers looking to reduce their dependency on external flash modules. Memory markets have always been volatile, but many analysts, according to Forbes, anticipate strong demand in flash during 2024, bolstered in part by new AI applications trying to create “all-flash object storage systems”. Consequently, smaller companies with less purchasing power could encounter serious issues sourcing modules or simply facing prices too high to make their products viable. Hence, many are looking to either reduce their external NAND needs or obliterate them altogether, which led us to offer NeoChromVG GPU in new STM32U5F9 and STM32U5G9 MCUs.

The NeoChromVG GPU solution

In essence, NeoChromVG GPU is a traditional Neochrom GPU with a hardware unit accelerating vector graphics computations, such as quadratic Bézier curves, which are very common in vector fonts, Bézier tessellation to render surfaces, and vector calculations for vertex transformation, among other things, to rapidly draw vector graphics on screen. It still relies on the same texture mapper as the regular Neochrom GPU and has similar features like L8 compression. Vector graphic acceleration simply becomes an additional tool in a developer’s arsenal to optimize their UI. The feature also comes on the heels of TouchGFX 4.23, which just gained support for vector fonts. Hence, engineers see the overarching strategy ST is using to help with memory dependency.

NeoChromVG GPU will be available on the new STM32U5G9 and STM32U5F9, the former being the version housing a crypto core. Both will feature 3 MB of RAM and 4 MB of dual-bank flash. This hardware configuration has enabled some of our customers to move to a single-chip design that didn’t require external memory at all, while the increase in internal memory and vector graphics support helped others use smaller NAND devices. In both cases, it helps simplify the PCB design to move to only four layers and lower the bill of materials. Similarly, as embedded systems tend to map their NOR memory for greater optimization, not having to map anything above 32 MB becomes a significant time saver.

The best way to start using vector graphics on STM32

Vector graphics aren’t for every system. Even with hardware acceleration, the performance penalty incurred by vector rendering may be too much in certain UIs. However, we are ensuring that developers get rapid prototyping tools to test NeoChromVG GPU in minutes. We are releasing the STM32U5G9J-DK, with a 480 x 480 display, and the STM32U5G9J-DK2 with an 800 x 480 screen, as well as a UI demo showing what developers can accomplish thanks to vector graphics. Even the ST Partner Riverdi, famous for its STM32 Embedded Displays, will soon offer a model with the STM32U5G9 to help develop and take advantage of the vector graphics accelerator.

From Chrom-ART to NeoChrom GPU What Are Chrom-ART and NeoChrom GPU?

Readers familiar with ST technologies can guess that NeoChrom GPU is the next evolution of Chrom-ART. The latter is a 2D accelerator (DMA2D) embedded inside several STM32 MCUs that optimizes memory access to manipulate images faster. Many tools and products from ST partners use it, such as Storyboard from Crank, Microvisor from Twilio, or interfaces from PsiControl, a TouchGFX Implementer, to only name three. Comparatively, NeoChrom GPU draws from the same philosophy while offering a greater scope of optimizations. Thanks to texture mapping with bilinear and point sampling, the new technology provides new drawing acceleration and supports animations. Hence, what used to require a Desktop PC GPU card can now run on a microcontroller.

How Does NeoChrom GPU Integrate Into the TouchGFX Ecosystem?

Historically, Chrom-ART represented one of ST’s first forays into graphical optimizations. Since then, we acquired TouchGFX and built an entire ecosystem with TouchGFX Designer, Simulator, and Generator. As a result, ST is integrating NeoChrom GPU into these tools right from the start. TouchGFX Designer contains demos showing a smooth animation running at 60 FPS on a circular display. More importantly, it shows the impact on the frame rate when NeoChrom GPU is off to help decision-makers grasp its importance. Similarly, the texture mapping widget will automatically use the new GPU if the MCU supports it. Hence, the immediate integration of the new IP within TouchGFX serves as a witness to ST’s cohesive ecosystem instead of a simple feature list.

From NeoChrom GPU to Real-World Performance What Are the Challenges to Graphical Performances?

 

 

 

 

 

 

The STM32U5

There exist two main challenges to graphical performances: an instructions-per-clock limitation and a memory issue. The first one often follows architectural innovations. Microcontrollers have ALU and FPU restrictions due to their size and low power consumption, but improvements in manufacturing processes allow for more transistors capable of handling more operations. NeoChrom GPU follows such trends with a hardware IP accelerating more types of graphical calculations. The second challenge is trickier but all the more critical because memory will always remain a scarce resource. While the STM32U599 will come with 2.5 MB of internal RAM capable of storing two frame buffers, many embedded systems need external RAM. The problem is that it comes with significant performance penalties.

What Are Unique STM32 Implementations?

To solve this second challenge, NeoChrom GPU comes with hardware optimizations specific to STM32 MCUs. For instance, the STM32U5 relies on either an 8-bit Octal Serial Peripheral Interface (OSPI) or a 16-bit high-speed interface (HSPI) at 200 MHz to external memory modules to hasten fetching operations to the L2 cache. Similarly, the L1 cache can directly access two 832 KB frame buffers in the internal RAM. As a result, tessellation is significantly faster thanks to quick access to all the data necessary to render the image in real-time. Put simply, our engineers optimized performance by working on reducing the time it takes to access textures and other assets, ultimately accelerating rendering by up to six times.

What’s Next?

The first industry feedback around NeoChrom GPU has been very positive. While many MCU makers have similar IPs to accelerate graphical computations, the specific STM32 optimizations and the TouchGFX ecosystem led many early alpha testers to adopt NeoChrom GPU instead of competing solutions. The new technology is already supported within TouchGFX 4.19, and a few alpha customers have already worked on production-ready UIs using an upcoming STM32U599 development kit. ST will also include NeoChrom GPU in other upcoming microcontrollers and we’ll update this blog post as they become public.

Conformance approval is a major step in bringing devices for the Internet of things (IoT) to the market. To ensure that these devices work properly, they need to be certified by testing laboratories accredited by certification bodies such as GCF, PTCRB or CTIA. With the successful verification of the 3GPP Rel. 17 NTN NB-IoT test cases in work item 333 at the CAG #77 meeting, using the R&S CMW500, the Global Certification Forum was able to activate the work item, kicking off conformance testing for NTN NB-IoT devices.

With this accomplishment, Rohde & Schwarz together with tier 1 chipset vendors like Qualcomm Technologies, Mediatek, and Sony Semiconductor Israel’s Altair and their respective platforms have contributed significantly to the adoption of non-terrestrial network-based IoT use cases spanning multiple sectors such as smartphone, consumer, automotive, agriculture, maritime, logistics, and mining. The NTN NB-IoT protocol test cases of work item 333 cover NTN-specific signaling aspects for NB-IoT devices as specified in 3GPP Rel.17 TS 36.523-1.

Rohde & Schwarz has equipped its market-leading NB-IoT solution with 3GPP Rel. 17 NTN features to provide the ecosystem with R&D, production, and conformance testing functions. The protocol conformance test cases were developed using the R&S CMW500 radio communication tester, which allows engineers to assess their NTN NB-IoT devices under realistic conditions, establishing a real-time, comprehensive connection with the simulated satellite network and testing the relevant signaling and RF scenarios in line with the 3GPP Rel. 17 specification. The test solution emulates geosynchronous orbit (GSO) and geostationary orbit (GEO) as well as low earth orbit (LEO) constellations. It helps engineers to verify NTN device challenges like time and frequency synchronization due to prolonged delay and Doppler effect, low Signal-to-Interference-plus-Noise Ratio (SINR), power saving mechanisms, satellite ephemerides, and GNSS acquisition, to name just a few of the core features.

The official GCF platform R&S CMW-IoT is a single box solution for conformance testing including PCT, RRM and RF. In addition to this, the single box also supports carrier acceptance testing.
