On March 10 2026, STMicroelectronics launched the ST64UWB family of ultra‑wideband (UWB) system‑on‑chip solutions, the first in the industry to support the upcoming IEEE 802.15.4ab standard. The family delivers extended range, higher processing power, and enhanced robustness for automotive, consumer, and industrial use cases such as digital key access, child‑presence detection, and radar‑based sensing.
The ST64UWB chips are fabricated on an 18 nm FD‑SOI process and integrate an Arm Cortex‑M85 core, AI acceleration, and digital signal processing for edge‑AI radar applications. The design also incorporates a narrow‑band assistance radio, enabling ultra‑precise ranging and sensing while maintaining low power consumption and high reliability in non‑line‑of‑sight scenarios.
The global UWB market is projected to grow from an estimated $1 billion in 2025 to over $3 billion by 2033, with a compound annual growth rate of 40% from 2023 to 2028 and 21.6% from 2025 to 2035. Key competitors in the automotive segment include Bosch, Qorvo, NXP, and Continental, while ST’s participation in the Car Connectivity Consortium and FiRa Consortium underscores its commitment to advancing UWB ecosystems.
"The ST64UWB family we announce today is an industry‑first system‑on‑chip supporting the latest ultra‑wideband specification, IEEE 802.15.4ab including narrow‑band assistance radio, with ultra‑precise ranging and sensing," said Rias Al‑Kadi, General Manager of the Ranging and Connectivity Division. "These chips are tailored for automotive, consumer, and industrial applications, providing innovators with a powerful platform for the next wave of ultra‑wideband use cases."
The launch expands STMicroelectronics’ connectivity portfolio and strengthens its position in automotive electrification and industrial automation, where high‑precision localization and secure access are becoming critical. By offering a comprehensive UWB solution, the company opens a new revenue stream in a rapidly expanding market segment and signals continued investment in next‑generation wireless technology.
