Application Scenarios & Design Considerations

8-BIT SINGLE-CHIP MICROCONTROLLERS

Alternative Part Number

  • AT89C4051-24SU --: Pin-compatible 8051-core MCU with 4KB flash in the same small package class, widely available and a common drop-in replacement for ST 8051 derivatives.
  • N76E003AT20 --: 8051-compatible MCU with 18KB flash and similar I/O and peripherals, offering a modern alternative when the original ST part is unavailable.
  • STC89C52RC-40I-PDIP --: Classic 8051-compatible MCU with 8KB flash, easy to source and often used as a functional substitute in legacy 8051 designs.
  • P89C51RD2 --: Classic 8051-compatible microcontroller with similar architecture and I/O structure, suitable for legacy Hynix 87C1404 applications requiring code porting.
  • W78E405 --: 8051-family MCU with comparable 4KB flash and pinout, often used as a substitute for older Hynix 87C series parts in embedded control boards.
