STMicroelectronics is offering cyber-protection to power-conscious connected devices with its new STM32L5 microcontroller (MCU) series featuring the Arm Cortex-M33 core.
Built 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, smartwatches, medical pumps or meters, and many others.
“The STM32L5 series with TrustZone and additional custom protection features considerably strengthens and hardens cyber-protection for small IoT devices,” said Ricardo De Sa Earp, Microcontroller Division General Manager, STMicroelectronics. “Also featuring our unique energy-saving technologies, rich connectivity, and smart digital and analog peripherals, these devices will be the first choice to host cutting-edge connected applications.”
STM32L5-series microcontrollers are sampling now and scheduled to begin production in the second quarter of next year.
