ST ST64UWB Cortex-M85 ultra-wideband SoC supports IEEE 802.15.4z and 802.15.4ab UWB standards, radar sensing

STMicroelectronics ST64UWB UWB solution for Automotive Consumer and Industrial Applications

STMicroelectronics ST64UWB Arm Cortex-M85 ultra-wideband (UWB) SoC family supports both the current IEEE 802.15.4z and the upcoming IEEE 802.15.4ab UWB standards for longer-range, more reliable positioning and secure proximity-based interactions. It mainly targets digital car keys, hands-free access, and smart-device detection. The family includes the ST64UWB-A100 (automotive entry), ST64UWB-A500 (automotive premium), and ST64UWB-C100 (industrial/smart home), all built on an 18 nm FD-SOI process that improves the RF link budget by ~3 dB, yielding roughly 50% additional range beyond what IEEE 802.15.4ab alone provides. The automotive-focused A-series offers ASIL-A(B) safety support, while the ST64UWB-C100 targets consumer and commercial applications. ST64UWB family specifications: MCU Core 32-bit Arm Cortex-M85 CPU with DP-FPU, MVE, and ETM Frequency Up to 100 MHz (ST64UWB-C100, ST64UWB-A100) Up to 256 MHz (ST64UWB-A500) Memory/Storage Integrated PCM Memory SRAM and Back-up SRAM Wireless Connectivity Ultra-wideband (UWB) Radio IEEE 802.15.4z-2020 and IEEE 802.15.4ab support UWB channels 5, 6, 8, 9, 10, […]

Turris Omnia NG Wired dual 10GbE, quad 2.5GbE router drops Wi-Fi for cost savings

Not everybody needs Wi-Fi in their router. That’s why Turris has now introduced the Omnia NG Wired dual 10GbE, quad 2.5GbE router without built-in Wi-Fi 7 connectivity to reduce costs. The specifications are the same as those of the earlier Turris Omnia NG Wi-Fi 7 router introduced last November, and it still features two 10 Gbps Ethernet SFP+ cages and four 2.5GbE RJ45 ports, but Wi-Fi 7 (and 5G cellular) connectivity is optional. Turris Omnia NG Wired (RTROM04-NGW) specifications: SoC – Qualcomm IPQ9574 (Networking Pro 820 Platform) quad-core Arm Cortex-A73 processor @ 2.2GHz Memory – 2 GB RAM Storage 8 GB eMMC storage M.2 socket for NVMe SSD Display – 240 × 240 px IPS color display Networking 2x 10 Gbps Ethernet SFP+ cages (WAN/LAN) 4x 2.5GbE RJ45 ports Optional WiFi 7 via upgrade kit Optional 4G LTE/5G cellular connectivity via mini PCIe slot and 2x SIM slots USB – […]

Nordic Semi unveils nRF54LS05A and nRF54LS05B entry-level, ultra-low-power Bluetooth LE SoCs

Nordic Semiconductor’s nRF54LS05A and nRF54LS05B are entry-level, ultra-low-power Bluetooth Low Energy (LE) Arm Cortex-M33 microcontrollers designed to be used as the main wireless SoC in simple applications such as sensors, tags, beacons, remotes, and PC peripherals, or operate as a Bluetooth LE companion device in more advanced products. Both SoCs are clocked at 128 MHz, feature Nordic’s 4th-generation Bluetooth LE radio, analog/digital interfaces, and advanced security. They also come with 0.5 MB of Non-Volatile Memory (NVM), and the only difference is that the nRF54LS05A is equipped with 64 KB of RAM, while the nRF54LS05B offers 96 KB. Nordic Semi nRF54LS05A/B specifications: CPU Arm Cortex-M33 core @ 128 MHz Performance – 250 CoreMark/mA @ 3V, 500 CoreMark Memory nRF54LS05A – 64 KB RAM nRF54LS05B – 96 KB RAM Storage – 508 KB NVM Wireless Bluetooth LE – 1 Mbps, 2 Mbps 2.4 GHz proprietary – GFSK: 4 Mbps, 2 Mbps, 1 […]

Dabao board features open-source hardware Baochip-1x RISC-V MCU (Crowdfunding)

An open-source hardware board usually features a closed-source microcontroller or processors, but the Dabao evaluation board goes further with the open-source Boachip-1x MCU, whose RTL files are available. It’s also manufactured in such a way that it is inspectable with the Infra-Red, In Situ (IRIS) technique, so users can look at the silicon and confirm they’ve got the right chip in a non-destructive way. Baochip-1x is a “general-purpose” microcontroller with a 350 MHz Vexriscv RV32-IMAC CPU core, a BIO accelerator for I/Os with four 700MHz PicoRV RV32-EMC CPU cores, 4MB of ReRAM, 2MB SRAM, a USB interface, various other I/Os, and hardware secure elements such as cryptography accelerators, key stores, one-way counters, true random number generation, and hardware attack countermeasures such as glitch sensors and a security mesh. The Dabao board itself is pretty basic with the microcontroller, two 16-pin headers for I/Os, a USB-C port for power and programming, […]

Renesas RA0E3 Arm Cortex-M23 MCU is a stripped-down RA0E1 for cost-sensitive applications

Back in 2024, Renesas first released the RA0E1, an ultra-low-power Cortex-M23 MCU designed for cost-sensitive applications, followed by the RA0E2, with extended temperature range support (-40°C to +125°C). The company has expanded its lineup with the RA0E3, a stripped-down version of the RA0E1 with less memory, fewer peripherals, and fewer GPIOs, designed for small and budget-focused applications for sensing, motor assist, safety, and basic system control. The MCU retains the same 32 MHz Arm Cortex-M23 (Armv8-M) core but now comes with 16KB flash and 2KB SRAM. It features an 8-channel 16-bit TAU timer, a 32-bit interval timer, a 10-bit ADC with a temperature sensor, a Data Transfer Controller, and serial interfaces including SPI, I²C, and UART (with LIN support). Additionally, it comes with up to 17 GPIOs, pull-ups, open-drain support, and built-in clock sources. It has an operating voltage range of 1.6V to 5.5V and supports −40°C to +125°C operation […]

GyroidOS virtualization solution aims to secure embedded devices, ease cybersecurity certification

Maintained by Fraunhofer AISEC, GyroidOS is an open-source, multi-arch OS-level virtualization solution designed for embedded devices with hardware security features, and aiming to support security certification processes such as Common Criteria (ISO/IEC 15408), DIN SPEC 27070 – IDS Trust Security profile, and IEC-62443 cybersecurity standards. The virtualization layer is based on Linux-specific features like namespaces, cgroups, and capabilities to provide isolation of different guest operating system stacks on top of a single, shared Linux kernel. It offers a much smaller footprint and additional separation of privileged instances compared to other container solutions, such as Docker. GyroidOS security features Container isolation based on a modularized OS-level virtualization layer Secure boot (e.g., UEFI on x86) Kernel module signing Signed GuestOSes (containers) Measured boot and remote attestation Full disk encryption coupled to TPM and secure boot Restriction of superuser in containers with Linux capabilities Fine-grained device access with device cgroups whitelists Secure Element […]

Android 17 Beta 1 released with H.266/VVC support, camera improvements, and more

Google has just announced the release of Android 17 Beta 1 with performance improvements, H.266/VVC video codec support, smoother camera mode transitions, privacy and security enhancements, and more. The company is not releasing Developer Previews anymore, and instead follows the “continuous Canary channel” announced with the first Android 16 Developer Preview. So, with Android 17, the very first release is the “Beta 1” release. Some of the key changes in Android 17 so far: Developers can’t opt out of orientation and resizability restrictions on large screen devices (sw > 600 dp), so they’ll have to make sure their apps work on tablets, foldables, and desktop windowing environments. With one exception: apps categorized as games with android:appCategory flag. Google published a separate blog post about the change. Performance improvements and tools Lock-free MessageQueue that will reduce missed frames. Added Generational garbage collection to ART’s Concurrent Mark-Compact collector. This aims to reduce […]

STMicroelectronics Stellar P3E quad-core Arm Cortex-R52+ automotive MCU features Neural-ART AI accelerator

Stellar P3E AI automotive MCU Block Diagram

STMicroelectronics has introduced the Stellar P3E, the first automotive MCU with an embedded Neural-ART AI accelerator, designed to simplify X-in-1 Electronic Control Units (ECUs) by consolidating powertrain functions like the inverter, on-board charger (OBC), and DC-DC converter into a single module. The MCU enables smart sensing, predictive maintenance, and virtual sensor applications without the cost and complexity of a separate SoC. The microcontroller features four 500 MHz Arm Cortex-R52+ cores with 19.5 MB of xMemory, which is based on phase-change memory (PCM), offering roughly twice the density of embedded flash. The chip integrates multiple ADC channels for precise sensing, high-resolution PWM down to 102 ps for fine motor control, and 10 timer modules for deterministic real-time operation. Connectivity options include Gigabit Ethernet and CAN-XL, for high-speed, low-latency in-vehicle communication. Stellar P3E (SR6P3EC4/SR6P3EC6) specifications: MCU – SR6P3EC4 / SR6P3EC6 CPU Cores – 4x Arm Cortex‑R52+ cores at up to 500 MHz; […]
