STMicroelectronics is bringing sophisticated cyber-protection to power-conscious connected devices with the new STM32L5 microcontroller series featuring the Arm Cortex-M33 core. Building on the Cortex-M33, which boosts protection for small devices by integrating Arm’s TrustZone hardware-based security, ST’s STM32L5-series MCUs add further enhancements including flexible software isolation, secure boot, key storage, and hardware cryptographic accelerators. They also provide rich functionality, high performance, and long run-times powered by coin cells or energy harvesting. Consuming as little as 33nA in shutdown mode and achieving 402 ULPMark-CP in the EEMBC ULPBench, the new MCU series builds on the Company’s expertise in low-power techniques such as adaptive voltage scaling, real-time acceleration, power gating, and multiple reduced-power operating modes proven in previous STM32L series.
With extensive integrated digital and analog peripherals, and consumer and industrial interfaces such as CAN FD, USB Type-C, and USB Power Delivery, STM32L5 MCUs provide an ideal platform for products such as industrial sensors or controls, home-automation devices, smart meters, fitness trackers, smart watches, medical pumps or meters, and many others.
