2 Min Read March 17, 2026
ST launches the ST64UWB chip family after MWC 2026, using AI and 18 nm FD‑SOI to integrate IEEE 802.15.4z and 4ab UWB standards.
Following Mobile World Congress 2026, on March 10, STMicroelectronics launched the ST64UWB family of Ultra-Wideband (UWB) chips. Aided by artificial intelligence (AI) and its 18 nm FD-SOI (Fully Depleted-Silicon on Insulator) process technology, ST64UWB is claimed to be the first solution to integrate the IEEE 802.15.4z and 4ab standards – promising best-in-class performance, enabling new use cases, and enhancing the user experience.
