STM8S207C8T3 Description

The performance line STM8S207C8T3 8-bit microcontrollers provides 32 to 128 Kbytes of Flash program memory. In the reference handbook for the STM8S microcontroller family, they are referred to as high-density devices.

The advantages of all STM8S207C8T3 devices include lower system costs, performance reliability, quick development times, and long product lifespans.

An integrated real data EEPROM with up to 300 k write/erase cycles and a high level of system integration with internal clock oscillators, a watchdog, and a brown-out reset lower the system cost.

The 20 MIPS at 24 MHz CPU clock frequency and improved characteristics, such as strong I/O, independent watchdogs (with a separate clock source), and a clock security mechanism, guarantee device performance.

Due to application scalability over a common family product architecture with compatible pinout, memory map, and modular peripherals, short development cycles are ensured.

A large selection of development tools is available with full documentation.

The STM8S family's sophisticated core, which is created using cutting-edge technology for applications with operating supplies ranging from 2.95 V to 5.5 V, ensures the longevity of their products.
