Application Scenarios & Design Considerations

FlashFlex51 MCU

Alternative Part Number

  • AT89C54-33PI --: Pin-compatible 8051-family microcontroller with 16KB flash, same 33 MHz speed grade and 40-pin PDIP package, widely available and a direct functional substitute.
  • W78E54B-40 --: 8051-compatible MCU with 16KB flash in 40-pin DIP, similar architecture and pinout, suitable drop-in replacement when 33 MHz timing margin allows the 40 MHz rated part.
  • P89C54X2BN --: 8051-core flash microcontroller with 16KB program memory in 40-pin DIP, comparable peripheral set and pinout, usable as an alternative with minor firmware verification.
