STM8S003F3P6TR 8-bit Microcontroller – 8KB Flash – TSSOP-20 – STMicroelectronics

The STM8S003F3P6TR from STMicroelectronics is a compact and cost-effective 8-bit microcontroller designed for high-performance, low-power embedded applications. Equipped with the reliable STM8 Harvard-architecture core, this MCU operates at speeds up to 16 MHz, making it suitable for a wide range of industrial, consumer, and control-oriented designs.

With 8 KB of Flash, 1 KB RAM, and 128 bytes of true data EEPROM (rated for 100,000 write/erase cycles), the STM8S003F3P6TR offers dependable non-volatile storage for configuration data. It supports a wide 2.95V to 5.5V operating range, allowing direct interfacing with standard 5V systems.

This device integrates essential peripherals including a 10-bit ADC (5 channels), multiple timers (16-bit advanced control, 16-bit general-purpose, and 8-bit basic), and communication interfaces such as UART/USART, SPI, and I²C. Additional features include brown-out detection, independent and window watchdog timers, enhancing system safety and reliability.

Packaged in a compact 20-pin TSSOP, the microcontroller is ideal for space-constrained PCB layouts and high-volume production designs.
