STM32L552和STM32L562微控制器采用运行于110 MHz的Arm® Cortex®‐M33处理器内核（支持面向Armv8-M、DSP和浮点单元（FPU）的TrustZone®技术），扩展了STM32超低功耗产品系列及其性能。
- STM32L552系列提供从256 KB 到512KB Flash存储器，提供48~144引脚封装。
- STM32L562提供了512 KB Flash存储器，还提供了额外的硬件加密加速引擎（AES、PKA和OTFDEC）。
所有封装均可选择使用或不使用嵌入式SMPS（DC/DC 降压调节器）。请参照数据摘要。
精选 视频
As part of our embedded online event, we had the pleasure of filming with Reinhard Keil, a Senior Director of Embedded Tools at ARM.
This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course. This is our first STM32 based on Cortex-M33 and its Trustzone and using specific ST security implementation - watch the video to find out more!
The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
