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.

Product types:
series
The new STM32U5 series combines the latest and most efficient Arm® Cortex®-M33 core with an innovative 40 nm platform that reduces energy consumption to the bone, while increasing performance. The series also adds the state-of-the-art features which are required in today’s applications, including advanced cyber security with hardware-based protection, and graphics accelerators for rich graphical user interfaces.
series
The STM32L5 series enhanced security features leverage Arm® Cortex®-M33 and its TrustZone® for Armv8-M. Thanks to this new core and a new ST ART Accelerator™ (also supporting external memory), the STM32L5 reaches a 443 CoreMark.
