Product overview
Description
The ST64UWB-A100 is the first monolithic next-generation automotive ultra-wideband solution from STMicroelectronics. It complies with IEEE 802.15.4ab and uses narrowband-assisted multi-millisecond ranging. Manufactured with 18 nm FDSOI technology, it provides a significantly improved link budget and robust, secure ranging, even in non-line-of-sight conditions.
The ST64UWB-A100 increases range by 50% while maintaining compatibility with legacy IEEE 802.15.4z. It can boost range by up to eight times when operating in IEEE 802.15.4ab mode.
The ST64UWB-A100 features an Arm® Cortex®-M85 core running at up to 100 MHz, integrated PCM and SRAM, automotive connectivity including FDCAN, and advanced security features compliant with SESIP Level 3, ISO 26262 (ASIL A), and AEC-Q100 Grade 2. It is a highly integrated, single-chip platform for secure, reliable, and cost-efficient ultra-wideband automotive applications.
