STM8S Mainstream series
ST’s STM8S series of mainstream 8-bit microcontrollers covers a large variety of applications in the industrial, consumer and computer markets, particularly where large volumes are concerned.
Based on the STM8 proprietary core, the STM8S series benefits from ST's 130 nm technology and advanced core architecture performing up to 20 MIPS at 24 MHz.
In addition to embedded EEPROM and RC oscillators, the rich number of I/Os offered and the performance of its embedded peripherals are recognized as differentiating key points versus competition.
The STM8S series is part of ST’s 10-year product longevity commitment program for STM32 and STM8 microcontrollers, ensuring a robust and reliable solution for designers.
The associated development toolchain from affordable discovery kits to more complex evaluation kits and third-party tools makes it easy to develop with STM8S microcontrollers.
The STM8S series consists of 4 lines, each with different features but with full compatibility and upgradability to simplify future design changes:
- STM8S Value line offers essential features set at the most affordable price and is now available in an 8-pin SO package.
- STM8S103/105 Access line offers more features and a larger variety of packages.
- STM8S207/208 Performance line features a full set of peripherals and provides performance for medium-to high-end applications.
- STM8S Application-specific line provides more analog features and dedicated firmware solutions.
