STM32L4系列超低功耗微控制器
意法半导体通过构建新型芯片架构实现了同类产品中最佳的超低功耗及性能，这得益于其应用设计上的高度灵活性。STM32L4 MCU在比较超低功耗微控制器效率的标准化EEMBC™ ULPBench® 测试中获得447 ULPMark-CP 和167 ULPMark-PP。此外，STM32L4系列打破了当前超低功耗领域的性能极限。基于带有FPU的Arm® Cortex®-M4内核以及意法半导体ART Accelerator™，该系列在80 MHz的CPU频率下性能达到100 DMIPS。
STM32L4系列可以根据微处理器运行时不同的应用需求来适时调整电压从而实现功耗的动态平衡。该功能适用于停止模式的低功耗外设（LP UART、LP定时器）、安全和保密特性、大量智能外设，以及诸如运算放大器、比较器、LCD、12位DAC和16位ADC（硬件过采样）等先进的低功耗模拟外设。
该系列包含不同的产品线：STM32L4x1（基本型系列），STM32L4x2（USB设备），STM32L4x3（USB设备, LCD），STM32L4x5（USB OTG）和STM32L4x6（USB OTG, LCD）。
为了简化STM32芯片间的移植操作和为用户提供所需的灵活性，STM32L4与不同的STM32系列均引脚兼容，为您打开了通往整个STM32生态体系的大门。

精选 视频
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.
MadeForSTM32™ is a new quality label delivered by ST, which is granted after an evaluation process. It helps engineers identify third party solutions with the highest level of integration and quality for the STM32 microcontrollers' ecosystem. MadeForSTM32™ is offered to members of the ST Partner Program who want to go one step further in our collaboration, with the overall objective of contributing to a high-quality STM32 ecosystem.
Getting started with STM32L4
- Purchase a 32-pin, 64-pin or 144-pin Nucleo board, Discovery kit or Evaluation kit for STM32L4 MCUs.
Download the STM32CubeL4 embedded software package containing the HAL, LL (low-layer) APIs, and middleware. Then install ST’s STM32CubeMX graphical software configuration tool that supports pinout configuration, code generation and a power consumption calculator. Start with one of the many examples provided or build your own project.
