Application Scenarios & Design Considerations

Mainstream Application specific line 8-bit MCU with 8 Kbytes Flash, 16 MHz CPU, integrated EEPROM

Alternative Part Number

  • STM8S003K3T6C --: Same STM8S family, LQFP32 package and pin-compatible core; lower flash (8KB vs 8KB) but suitable for many applications needing a cost-reduced drop-in with similar peripherals.
  • STM8S103K3T6C --: STM8S series LQFP32 device with 8KB flash and comparable peripherals; widely available and often used as a functional substitute when the 903 variant is unavailable.
  • PIC16F886-I/SS --: Alternative 8-bit MCU in a comparable 28-pin package with similar GPIO, timers and ADC resources; requires firmware porting but offers a second-source option outside the STM8 family.
  • PIC16F886-I/PT --: Alternative 8-bit MCU in a 32-pin TQFP package with similar GPIO, ADC and timer resources; requires firmware porting but is a viable cross-vendor replacement.
