STMicroelectronics Launches First Automotive-Grade UWB Ranging Chip, ST64UWB

On March 10, STMicroelectronics launched the ST64UWB, the industry’s first automotive-grade ultra-wideband (UWB) chip compliant with the IEEE 802.15.4ab standard, targeting automotive, consumer electronics, and industrial applications. The chip offers extended range, enhanced processing power, and greater stability, supporting features such as secure digital access, human presence detection, and high-precision proximity sensing. Leveraging Multi-Millisecond Ranging (MMS) and Narrowband Assistance (NBA) technologies, it improves connection reliability when devices are inside bags or pockets and strengthens critical in-cabin applications like Child Presence Detection (CPD)—a feature endorsed by Euro NCAP as a potentially life-saving technology. Samples are now available to key Tier-1 suppliers and automakers.
