The STMicroelectronics STM8S103F2M6 is a cost-effective 8-bit microcontroller in a 20-pin SOIC package. It features 4KB of Flash and 1KB of RAM, running at up to 16MHz. With a supply voltage range of 2.95V to 5.5V, it is designed for 5V applications. It includes brown-out reset, power-on reset, PWM, and a watchdog timer, making it ideal for simple control tasks.

  • 5V Compatibility: Directly interfaces with 5V logic and sensors without level shifting.
  • Compact SOIC-20: Saves board space in cost-sensitive designs.
  • Low Cost: Optimized for high-volume consumer and industrial applications.
  • Robust Protection: BOR and WDT enhance system reliability in noisy environments.

Small Motor Drivers

The 5V operation and PWM outputs make it suitable for driving small DC motors in toys and pumps.

LED Lighting Controllers

With 4KB Flash, it can implement simple PWM dimming and color control for RGB LED strips.

Power Supply Monitoring

Its 5.5V input tolerance allows direct connection to 5V rails for overvoltage/undervoltage detection.

Automotive Aftermarket Accessories

The wide voltage range and -40°C to +85°C rating support car alarm sensors and window controllers.

Home Appliance Timers

It can manage wash cycle timers and buzzer drivers in washing machines and microwaves.

Simple Industrial Relays

The robust I/O and WDT ensure reliable operation in relay logic controllers for conveyor belts.
