STM32L5 - Ultra-low-power MCUs, Enhanced Security for IoT and Embedded Applications

安全性已经成为嵌入式和物联网应用开发人员正在努力改进的三个关键领域之一。STM32L5微控制器系列是在性能、功耗和安全性之间实现新的最佳平衡的解决方案。STM32L5系列MCU利用了Arm Cortex-M33处理器的安全特性，并将其面向Armv8-M架构的TrustZone与意法半导体安全实现方案相结合。意法半导体专利的超低功耗技术创造了一流的节能型微处理器，可用于物联网(IoT)、医疗、工业和消费等低功耗应用。

STM32L5系列微控制器可提供最高512 KB的（双Bank）闪存和256 KB的SRAM，通过采用新型内核和全新的意法半导体 ART Accelerator™（现在也支持外部存储器），实现了性能大幅提升(443 CoreMark)。

STM32L5通过7种封装选项（48~144个引脚）提供众多产品型号，还支持高达125°C的工作环境温度。
