  • More Security with TrustZone Security and ST Security Implementation
  • Lower Power Consumption
  • Integration, Size, Performance : More performance, Large Memory Size and Wide Portfolio
  • A Full Set of Security Options

Security has emerged as one of the 3 key areas that developers of embedded and IoT applications are thriving to improve. The STM32L5 microcontroller series is the solution and provides a new optimal balance between performance, power, and security. The STM32L5 MCU series harnesses the security features of the Arm Cortex-M33 processor and its TrustZone for Armv8-M combined with ST security implementation. ST-proprietary ultra-low-power technologies create a class-leading MCU for energy-conscious applications such as the Internet of things (IoT), medical, industrial and consumer.
