Connect With Us


March 27, 2025 - Mouser Electronics, Inc., the industry's leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the STM32U3 ultra-low-power 32-bit microcontrollers from STMicroelectronics.

STMicroelectronics STM32U3 series consists of ultra-low-power Arm® Cortex®-M33 32-bit microcontrollers with TrustZone® and a Floating-Point Unit (FPU), operating at up to 96MHz. The single‑precision FPU supports all the Arm data‑processing instructions and data types. The Cortex-M33 core also implements a full set of digital signal processing (DSP) instructions and a memory protection unit (MPU) that enhances application security. Based on near-threshold voltage technology, the STM32U3 devices reduce the active consumption down to 10µA/MHz, resulting in far longer battery life for any application.

The STM32U3 MCUs are ideal for battery-powered devices, automotive applications, industrial automation, consumer electronics, healthcare and medical devices, security and access control, smart grids and meters, and other ultra-low-power applications.
