概述
高密度值线STM8L05xxx器件是STM8L超低功耗8位系列的成员。
价值线STM8L05xxx超低功耗系列具有增强型STM8 CPU核心，提供更高的处理能力(在16 MHz时高达16 MIPS)，同时保持CISC架构的优势，具有改进的代码密度，24位线性寻址空间和针对低功耗操作的优化架构。
该系列包括一个集成的调试模块与硬件接口(SWIM)，允许非侵入式的应用程序内调试和超快的Flash编程。
高密度值线STM8L05xxx微控制器具有嵌入式数据EEPROM和低功耗，低电压，单电源程序闪存。
所有器件都提供12位ADC，实时时钟，四个16位定时器，一个8位定时器以及标准通信接口，如两个spi, I2C，三个USARTs和8x24或4x28段LCD。
STM8L05xxx系列工作电压为1.8 V至3.6 V，可在-40至+85°C温度范围内使用。
外设的模块化设计允许在不同的意法半导体微控制器系列(包括32位系列)中找到相同的外设。
所有价值线STM8L超低功耗产品都基于相同的架构，具有相同的内存映射和一致的引脚。
