STM8L050J3, STM8L051F3, STM8L052C6, STM8L052R8 MCUs
and STM8L151/L152, STM8L162, STM8AL31, STM8AL3L lines
Introduction
This reference manual targets application developers. It provides complete information on
how to use memory and peripherals on STM8L050J3, STM8L051F3, STM8L052C6,
STM8L052R8 MCUs and STM8L151/L152, STM8L162, STM8AL31, STM8AL3L lines.
STM8Lxxx and STM8ALxx microcontrollers lines include families with different memory
densities, packages and peripherals. These products are designed for ultra-low-power
applications. Refer to the product datasheets for the complete list of available peripherals.
For ordering information, pin description, mechanical and electrical device characteristics,
refer to the product datasheets. For information on the STM8 SWIM communication protocol
and debug module refer to the user manual (UM0470). For information on the STM8 core,
refer to the STM8 CPU programming manual (PM0044). For information on programming,
erasing and protection of the internal Flash memory refer to the STM8L Flash programming
manual (PM0054).
