STM32L1系列超低功耗微控制器
意法半导体基于Arm® Cortex®-M3的STM32L1系列采用意法半导体专有的超低漏电流制程,具有创新型自主动态电压调节功能和5种低功耗模式,为各种应用提供了无与伦比的平台灵活性。STM32L1系列扩展了超低功耗的理念,并且不会牺牲性能。
与STM32L0及STM8L一样,STM32L1提供了动态电压调节、超低功耗时钟振荡器、LCD接口、比较器、DAC及硬件加密功能。
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。
这种创新型架构(电压调节、超低功耗MSI振荡器)能够以极低的功耗预算为您的设计实现更高的性能。大量嵌入式外设,例如USB、LCD接口、运算放大器、比较器、具有快速开/关模式的ADC、DAC、电容触摸和AES,为STM32L1系列提供了一个能够满足您的所有要求的可扩展平台。
该系列包含4款不同的型号:STM32L100超值型、STM32L151、STM32L152(LCD)和STM32L162(LCD和AES-128)。
为了简化移植步骤和为您提供所需的全部灵活性,STM32L1与各款STM32F系列均引脚兼容,为您打开了通往整个STM32生态体系的大门。
- 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

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.
