STMicroelectronics (STM) Debuts Industry-First ST64UWB Family for Automotive Ranging

STMicroelectronics (NYSE:STM) is one of the hot EV stocks to buy now. On March 10, STMicroelectronics introduced the ST64UWB family, the industry’s first integrated system-on-chip solutions to support the upcoming IEEE 802.15.4ab ultra-wideband standard alongside the existing IEEE 802.15.4z specification. Built using 18 nm FD-SOI technology, these chips offer superior RF performance and a nearly 3dB boost in link budget, extending signal range beyond previous generations. This new family is designed to provide high-precision ranging and sensing for a wide array of automotive, consumer, and industrial applications.

The ST64UWB series introduces technical enhancements like multi-millisecond ranging and narrowband assistance, which improve connection stability when devices are obstructed, such as in a back pocket or bag. For the automotive sector, the ST64UWB-A chips support safety-critical features like child presence detection and precise vehicle localization, with some models featuring AI acceleration for advanced radar use cases.

Industry leaders and Tier 1 suppliers are already sampling these devices and noted that the IEEE 802.15.4ab standard offers more than 8x the range of its predecessor. Because the ST64UWB family maintains backward compatibility with the 802.15.4z ecosystem, manufacturers can adopt these performance and cost-efficiency improvements without disrupting existing deployments. For this transition, STMicroelectronics (NYSE:STM) is providing comprehensive development kits that include a full UWB stack, radar toolboxes, and reference designs to accelerate the adoption of next-gen UWB tech.

STMicroelectronics (NYSE:STM), together with its subsidiaries, designs, develops, manufactures, and sells semiconductor products in Europe, the Middle East, Africa, the Americas, and the Asia Pacific.
