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。

Discover the large and pin-to-pin compatible STM32 ultra-low-power portfolio. This offer covers more than 2 billion of applications like IoT, Industrial sensors, wearables & home automation.
In our continued efforts to simplify developers’ life within the STM32Cube environment, we just introduced a new video demonstrating how to easily port an example built using ST’s new STM32Cube Low-Layer APIs from one board (NUCLEO-L476RG) to another (32L496GDISCOVERY) within the same STM32 family.
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.
