STM8S903F3M6         Description

 The STM8S903K3/F3 access line 8-bit microcontroller provides 8K-byte flash program memory and integrated real-world data EEPROM. The STM8S Microcontroller Series reference Manual (RM0016) refers to the devices in this series as low density. They have the following advantages: performance, robustness, and reduced system costs. The state-of-the-art core and peripherals manufactured with state-of-the-art technology, 16 MHz clock frequency, powerful Istroke O, independent watchdog with independent clock source and clock safety system ensure the performance and robustness of the device. System costs are reduced due to the integration of real data EEPROM that can support up to 300k write / erase cycles, as well as high system integration with internal clock oscillators, watchdogs and power-off resets.
