Application Scenarios & Design Considerations

5V RANGE 8-BIT MCU WITH 8 TO 32K FLASH/ROM, 10-BIT ADC, 4 TIMERS, SPI, SCI INTERFACE

Alternative Part Number

  • STM8S003K3T6 --: Pin-compatible 8-bit MCU from ST's STM8S series with similar LQFP32 package and peripherals; a common migration path from the ST72F series.
  • PIC16F877A-I/PT --: Widely available 8-bit MCU in TQFP44 with comparable GPIO, timers, and ADC resources; suitable functional replacement with minor redesign.
  • AT89C51RD2-IM --: 8051-core 8-bit MCU in TQFP44 offering similar embedded control capability and broad availability as a fallback alternative.
  • STM8S105K4T6 --: Pin-compatible 8-bit MCU from ST's newer STM8S family with similar Flash/RAM and peripherals; a common migration path from ST7 devices.
  • ATMEGA48PA-AU --: Widely available 8-bit AVR MCU in the same 32-pin TQFP package with comparable Flash and I/O, suitable for redesigns needing a second source.
  • PIC16F1936-I/PT --: 8-bit PIC MCU in 44-pin TQFP with comparable memory and peripherals; a viable alternative when porting the application to a different architecture.
