Programming manual

STM8 CPU programming manual

Introduction

The STM8 family of HCMOS microcontrollers is designed and built around an enhanced

industry standard 8-bit core and a library of peripheral blocks, which include ROM, Flash,

RAM, EEPROM, I/O, Serial Interfaces (SPI, USART, I2C,...), 16-bit Timers, A/D converters,

comparators, power supervisors etc. These blocks may be assembled in various

combinations in order to provide cost-effective solutions for application-specific products.

The STM8 family forms a part of the STMicroelectronics 8-bit MCU product line, which finds

its place in a wide variety of applications such as automotive systems, remote controls,

video monitors, car radio and numerous other consumer, industrial, telecom, and multimedia

products.
