STM8S103F3P6 8-bit microcontroller, 16MHz STM8 MCU with 8KB Flash
The STM8S103F3P6 from STMicroelectronics is a cost-effective 8-bit microcontroller featuring a 16MHz STM8 core with 8KB Flash memory and 1KB RAM, designed for industrial control, consumer electronics, and embedded systems. This MCU operates within a 2.95V to 5.5V voltage range, supporting flexible power supply configurations while consuming low current (5.4mA active mode @ 16MHz). It integrates 10-bit ADC, 16-bit timers, UART, SPI, and I²C interfaces, enabling robust peripheral connectivity in compact designs. Packaged in a 20-pin TSSOP, it offers high integration density for space-constrained applications. The 10,000 write-cycle Flash endurance and industrial temperature range (-40°C to +85°C) ensure reliability in demanding environments.
STM8S103 series STM8S103F3P6 Key Features

● Memory Configuration: 8KB Flash + 1KB RAM + 128B EEPROM for data retention
● Rich Peripheral Set: 4-channel 10-bit ADC, 3x16-bit timers, UART/SPI/I²C communication
● Flexible Power Management: Low-power modes (Wait/Halt/Active-Halt) with <1µA standby current
● Robust Packaging: 20-pin TSSOP (4.4mm x 6.5mm) with 15 programmable GPIOs
● Enhanced Durability: 10kV ESD protection and 10k Flash write cycles for industrial use
Applications
This microcontroller excels in appliance control boards (washing machines, coffee makers), lighting systems, motor drivers, and simple IoT nodes. Its analog peripheral integration makes it ideal for sensor interfaces, while the serial communication options enable modular system designs. The combination of low power and robust packaging suits battery-operated devices and industrial control modules.
Selection Advantages
The STM8S103F3P6 delivers exceptional cost-performance ratio for basic control applications. Unlike competing 8-bit MCUs, it offers superior clock speed (16MHz vs typical 8MHz) and larger memory (8KB Flash) while maintaining pin-compatibility with legacy designs. The integrated EEPROM eliminates need for external memory chips, and ST's proven development tools (STVD, STM8Cube) accelerate time-to-market. Its 5V tolerance simplifies migration from older 5V systems.
