除了超低功耗MCU这个特点之外，STM32L1系列还提供了广泛的功能特性、存储容量和封装引脚数选项。该系列产品提供32~512 KB Flash存储器（支持最高可达
80 KB的SDRAM和16 KB真正的嵌入式EEPROM）和48~144个引脚，凸显其功耗超低和性能高的特点。
- 超低功耗模式：280 nA，具有备份寄存器（3个唤醒引脚）
- 超低功耗模式 + RTC：900 nA，具有备份寄存器（3个唤醒引脚）
- 低功耗运行模式：低至9 μA
- 动态运行模式：低至177 μA/MHz
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.
The STM32Cube.AI is an extension pack of the widely used STM32CubeMX configuration and code generation tool enabling AI on STM32 Arm® Cortex®-M-based microcontrollers.
Getting started with STM32L1
- Purchase a 64-pin Nucleo board, Discovery kit or Evaluation kit for STM32L1 MCUs.
- Download the Free STM32CubeL1 embedded software package containing the HAL, LL (low-layer) APIs, and middleware. Then install ST’s Free 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.
STM32L1 Low power Wireless Solution (Sigfox)
To discover low-power wireless solutions based on the STM32L1, the STEVAL-FKI433V1 (430 – 470 MHz) and the STEVAL-FKI868V1 (860 - 940 MHz) development kit based on Spirit2 low-power Sub-GHz transceiver are now available.
