ST’s ultra-low-power MCU platform is based on a proprietary ultra-low-leakage technology and optimized design.
STM32 ultra-low power microcontrollers offer designers of energy-efficient embedded systems and applications a balance between performance, power, security, and cost effectiveness. The portfolio includes, the STM32L0 (Arm® Cortex®-M0+), the STM32L4 (Arm® Cortex ®-M4) and the STM32L5 MCU (Arm® Cortex®-M33).
The STM32U5 series (Arm® Cortex®-M33) with its best-in-class power consumption and enhanced security features is the latest addition to this rich portfolio.
