Application Scenarios & Design Considerations

Mainstream Access line 8-bit MCU with 4 Kbytes Flash, 16 MHz CPU, integrated EEPROM

Alternative Part Number

  • STM8S003F3P6 --: Same STM8S family, pin-compatible TSSOP-20 8-bit MCU with 8KB flash; lower-cost value line and a common drop-in substitute for STM8S103F3P6TR in most designs.
  • PIC16F1824-I/ST --: Pin-compatible TSSOP-20 8-bit MCU with comparable flash, RAM and peripherals; a viable cross-vendor alternative when ST supply is constrained, though firmware must be ported.
  • ATMEGA328P-AU --: Widely available 8-bit AVR MCU in TSSOP-32 with similar flash and peripheral set; suitable as a functional alternative for redesigns, requiring layout and firmware changes.
