IEEE 802.15.4ab UWB

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

ST’s next-generation UWB portfolio brings precise long-range distance measurement and high-resolution radar together in a single chip, helping unlock more seamless hands-free access and new safety features. It supports both the upcoming IEEE 802.15.4ab and 802.15.4z (FiRa) standards, giving carmakers a clear path to scale next-generation UWB across future vehicle platforms. With next-generation UWB expected to power 80% of UWB-enabled cars by 2030, the new ST64UWB family is built to help accelerate adoption and get ahead of the transition.

ST64UWB-A series: designed for automotive

Hands-free access

More reliable hands-free car access. Narrowband-assisted ranging delivers far greater range and more accurate digital key detection.

Child presence detection

A high-resolution radar engine enables advanced in-cabin presence detection, from child occupancy alerts to seat-belt detection, and smart cabin monitoring.

Kick sensing

Open the trunk with a simple gesture, without touching a handle, even when your arms are full, using radar-based gesture recognition.

With extended range, greater processing power, and integrated radar, the ST64UWB-A series supports automotive access, in-cabin safety, and hands-free convenience.
