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

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,

ST launches 800 MHz STM32V8 Arm Cortex-M85 high-performance MCU manufactured with 18nm FD-SOI process

ST has just launched its most powerful STM32 microcontroller so far, with the STM32V8 family, the first equipped with a Cortex-M85 core (clocked at up to 800 MHz) and manufactured with an 18nm FD-SOI process. It's a non-pin compatible update to the STM32H7 family that delivers up to 5,072 CoreMarks, greatly improves Edge AI performance thanks to Arm Helium and MVE, integrates up to 4MB eNVM (Embedded NVM), operates up to 140°C, and adds PCM (phase-change memory) radiation immunity. Two main parts have been launched in different configurations and packages: STM32V863 and STM32V873. STM32V863/873 specifications: Core – 32-bit Arm Cortex-M85 CPU @ up to 800MHz with Arm Helium, Arm MVE, TrustZone...; up to 5,072 CoreMarks Multimedia accelerators - Chrom-ART 2D GPU, and JPEG hardware accelerator Memory/Storage 1.5 MB system SRAM with ECC (partial) 8 KB backup RAM 192 KB zero-wait state TCM Up to 512 KB TCM with ECC Up

Решение проблемы мертвого времени с помощью Copilot

Этой проблеме я уже посвятил две статьи. Ну, как проблеме — проблеме для меня. Никак не удавалось охватить её целиком, когнитивно и ментально промоделировать. Появление Copilot кардинально всё изменило — ментальные границы раздвинулись, и здесь я выкладываю окончательное решение для семейств микроконтроллеров Synergy и RA8 от Renesas.
