Reference manual
STM8L051/L052 Value Line, STM8L151/L152, STM8L162,
STM8AL31, STM8AL3L MCU lines
Introduction
This reference manual targets application developers. It provides complete information on
how to use STM8L051/L052 Value Line, STM8L151/L152, STM8L162, STM8AL31 and
STM8AL line microcontroller memory and peripherals. STM8Lxxx line and STM8ALxx line
microcontrollers 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,
please refer to the product datasheets. For information on the STM8 SWIM communication
protocol and debug module, please refer to the user manual (UM0470). For information on
the STM8 core, please refer to the STM8 CPU programming manual (PM0044). For
information on programming, erasing and protection of the internal Flash memory please
refer to the STM8L Flash programming manual (PM0054).

STM8AL3188, STM8AL3L8A, STM8AL3L89, STM8AL3L88 microcontrollers with 64-KB
Flash.
High-density STM8AL31E88 and STM8AL3LE88 devices: STM8AL31E88,
STM8AL3LE88 microcontrollers with 64-KB Flash (same peripheral set as high-density
STM8AL318x and STM8AL3L8x plus the AES hardware accelerator).
High-density STM8L15xx devices: STM8L151C8/M8/R8 and the STM8L152C8/M8/R8
microcontrollers with 64-KB Flash (Same peripheral set as medium+).
High-density STM8L16xx devices: STM8L162M8/R8 microcontrollers with 64-KB Flash
(Same peripheral set as high-density STM8L152 devices plus the AES hardware
accelerator).
