Introduction

This document describes the features, pinout, mechanical data and ordering information for

the low density STM8L051F3 microcontroller with 8-Kbyte Flash memory density.

For further details on the whole STMicroelectronics low density family please refer to

Section 2.2: Ultra-low-power continuum.

For detailed information on device operation and registers, refer to the STM8L050J3,

STM8L051F3, STM8L052C6, STM8L052R8 MCUs and STM8L151/L152, STM8L162,

STM8AL31, STM8AL3L lines reference manual (RM0031).

For information on to the Flash program memory and data EEPROM, refer to the How to

program STM8L and STM8AL Flash program memory and data EEPROM programming

manual (PM0054).

For information on the debug module and SWIM (single wire interface module), refer to the

STM8 SWIM communication protocol and debug module user manual (UM0470).

For information on the STM8 core, refer to the STM8 CPU programming manual (PM0044).
