ST64UWB: premium hands-free access and presence detection
Industry-first chips supporting the upcoming IEEE 802.15.4ab UWB standard
All-in-one UWB chip: outstanding range and precision
All-in-one UWB chip: outstanding range and precision
ST’s next‑generation UWB portfolio combines precise long‑range distance measurement and high‑resolution radar in a single chip. Supporting both the upcoming IEEE 802.15.4ab and 802.15.4z (FiRa) standards, the new ST64UWB series unlocks superior hands‑free access and next‑generation safety features, including child‑presence detection.
ST64UWB family: designed for automotive, consumer and industrial
Automotive
ST64UWB-A series ICs deliver extended range and greater processing power for automotive applications. Secure connected use cases include digital key access and precise vehicle localization. Advanced radar sensing features unable reliable child presence detection (CPD), in-cabin monitoring at the edge, and kick sensing for hands-free trunk opening.
Consumer & industrial
ST64UWB-C series ICs deliver extended range and greater processing power for consumer and industrial applications. Use cases include superior hands-free home access and Aliro-enabled smart locks. Presence and motion sensing, as well as centimeter-level localization, support smart lighting, security systems, and asset tracking.
Achieve more with a single UWB anchor
Seamless hands‑free access
Reliable entry even when devices are in bags or pockets, enabling a true "just walk up and it works" experience for cars, smart locks, and building access.
Hardware-grade trust
SESIP Level 3 Enclave protects digital keys and credentials entirely on-chip, with no reliance on external secure elements.
Lower cost and design complexity
Fewer anchors cut BOM, wiring, and installation effort, while the full application stack runs on-chip to reduce system complexity.
