MCUs Deliver Hardware-Based IoT Security
STMicroelectronics this week launched the STM32L5 microcontroller, which builds on the Cortex-M33 hardware-based security with its own enhancements such as flexible software isolation, secure boot, key storage and hardware cryptographic accelerators. It is aimed at power conscious connected devices, utilizing 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. This enables it to provide 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.
