The STM8S103F3P6 from STMicroelectronics is an 8-bit microcontroller built on the STM8 core. It operates at up to 16 MHz with 8 KB of flash and 1 KB of RAM. The device supports a wide voltage range of 2.95V to 5.5V and includes essential peripherals like PWM, WDT, and brown-out reset. Housed in a compact 20-pin TSSOP package, it is designed for cost-sensitive embedded applications.

  • Wide voltage range: Operates from 2.95V to 5.5V, simplifying power supply design.
  • Integrated peripherals: PWM, WDT, and POR reduce external component count.
  • Compact package: 20-TSSOP saves PCB area for space-constrained designs.
  • Proven STM8 core: Reliable 8-bit architecture with extensive toolchain support.

Industrial Control

Use the STM8S103F3P6 for simple motor control or sensor interfacing. Its 16 MHz core and PWM peripherals handle real-time tasks efficiently.

Consumer Electronics

Ideal for remote controls, small appliances, and toys. The low 2.95V minimum voltage allows battery operation.
