  "textContent": "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, [...]\n\nThe post ST ST64UWB Cortex-M85 ultra-wideband SoC supports IEEE 802.15.4z and 802.15.4ab UWB standards, radar sensing appeared first on CNX Software - Embedded Systems News.",
