概述

STM8L050J3是STM8L超低功耗8位系列的成员。

STM8L050J3具有增强的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。

STM8L050J3 MCU包括一个集成调试模块和一个硬件接口(SWIM)，允许非侵入式应用程序内调试和超快速Flash编程。

该器件集成了广泛的增强型I/ o和外设，一个12位ADC，两个比较器，一个实时时钟，两个16位定时器，一个8位定时器，以及标准通信接口，如SPI, I2C接口和一个USART。

外设的模块化设计允许该设备具有相同的外设，可以在不同的意法半导体微控制器系列中找到，包括32位系列。

STM8L050J3作为所有价值线的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。
