STM32L1 系列

STM32 L1系列超低功耗微控制器

意法半导体基于ARM® Cortex™-M3的STM32 L1系列采用意法半导体专有的超低泄漏制程,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。STM32 L1系列扩展了超低功耗的理念,并且不会牺牲性能。

与STM32 L0及STM8L一样,STM32 L1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以外,STM32 L1系列还提供了多种特性、存储容量和封装引脚数选项。该系列产品提供32~512KB Flash存储器(高达

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STM32 L1系列提供了一个可扩展平台,能够满足您的所有要求。


为了简化移植步骤和为您提供所需的灵活性,STM32 L1与不同的STM32 F系列均引脚兼容,为您打开了通往整个STM32体系的大门。
