Application Scenarios & Design Considerations

8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY, ADC, 16-BIT TIMERS, SPI, SCI INTERFACES

Alternative Part Number

  • STM8S003F3P6 --: STM8S series is ST's modern 8-bit MCU line that replaces the older ST7 family; similar 20-pin TSSOP package, 8KB flash, and comparable peripherals, making it a strong drop-in upgrade path.
  • AT89C4051-24PU --: Classic 8051-compatible 8-bit MCU in a 20-pin DIP with 4KB flash and similar I/O count; widely available and functionally similar for legacy 8-bit control applications.
  • PIC16F628A-I/P --: Popular 18-pin 8-bit MCU with comparable I/O, timers, and USART; a common cross-vendor alternative when the ST7 series is unavailable, though pinout and code require adaptation.
  • PIC16F877A-I/P --: General-purpose 8-bit MCU with comparable I/O, timers, and memory size; a well-supported alternative if firmware porting is acceptable.
  • AT89C51RC2-IM --: Classic 8051-core 8-bit MCU with similar pin count and peripheral set, suitable as a functional substitute for legacy designs.
