STM32U3 Ultra-Low-Power 32-Bit Microcontrollers

STMicroelectronics STM32U3 Ultra-Low-Power Arm® Cortex®-M33 32-Bit Microcontrollers with TrustZone® and a Floating-Point Unit (FPU) operate at up to 96MHz. The single‑precision FPU supports all the Arm single‑precision 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.
