STM32U0 Series

The latest generation of entry level ultra-low power MCUs

By incorporating best-in-class static consumption and multiple ultra-low-power modes, the STM32U0 series offers significant energy savings and a longer usage life.

The series is based on the Arm Cortex®-M0+ core running up to 56 MHz and targets SESIP Level 3, PSA-Certified Level 1, and NIST certifications.

STM32U0 contributes to a more sustainable approach
