STM8S003F3P6

The STM8S003F3P6 from STMicroelectronics is an 8-bit microcontroller based on the STM8 core, offering 16MHz operation with 8KB Flash, 1KB RAM, and 128-byte EEPROM in a compact TSSOP-20 package. It features a comprehensive peripheral set including UART, SPI, I2C, 10-bit ADC, and multiple timers. The internal 16MHz RC oscillator provides 1% accuracy without external components. With in-circuit and in-application programming support, it enables flexible firmware updates in the field.

The STM8S003F3P6 is based on the STM8 8-bit core with Harvard architecture and a 3-stage instruction pipeline for efficient code execution at 16MHz. The CPU accesses Flash, RAM, and EEPROM through separate address spaces. Peripherals are connected via the internal bus and include UART for asynchronous serial communication, SPI for high-speed synchronous communication, I2C for multi-device bus communication, and ADC for analog signal conversion. Timers provide PWM generation, input capture, and timing functions. The device supports multiple low-power modes including wait, active-halt, and halt for power optimization.
