The STM8S903F3P6TR is a mainstream application-specific 8-bit microcontroller from STMicroelectronics. It is built around an advanced STM8 core with a Harvard architecture and a 3-stage pipeline, operating at a 16 MHz clock frequency.
This MCU offers 8 Kbytes of Flash program memory with a data retention of 20 years at 55 °C after 10 kcycles. It also includes 640 bytes of true data EEPROM with an endurance of 300 k write/erase cycles, and 1 Kbyte of RAM. Key features include a nested interrupt controller, multiple timers (advanced control, general purpose, basic, watchdog), and communication interfaces such as UART, SPI (up to 8 Mbit/s), and I2C (up to 400 kbit/s).
For analog interfacing, it provides a 10-bit ADC with up to 7 multiplexed channels. The device is available in a 32-pin package, offering up to 28 I/Os. Power management features include low-power modes like wait, active-halt, and halt, with the ability to switch off peripheral clocks individually. A clock security system with a clock monitor and internal low-power 128 kHz RC oscillator are also integrated, along with power-on and power-down reset functionalities.
