STMicroelectronics STM32U0 Entry Level Ultra-Low Power Microcontrollers (MCUs)
Based on the Arm Cortex®-M0+ core running up to 56 MHz
The STM32U0 series of microcontrollers is the latest generation of STMicroelectronics’ entry level, ultra-low power MCUs. 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.
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 STM32U0 series offers a more sustainable approach by significantly reducing energy consumption compared to previous generations. Its enhanced energy management capabilities allow for longer product lifetimes, enabling batteries to last up to twice as long, depending on the application.
Designed specifically for entry-level, battery-powered devices, the STM32U0 is an ideal solution for projects prioritizing energy efficiency and extended battery life.
