Application Scenarios & Design Considerations

FlashFlex51 MCU

Alternative Part Number

  • AT89C51RD2-IM --: Pin-compatible 8051-family MCU with 64KB flash, similar to the SST89E516RD2 in the same 8051 ecosystem; Microchip acquired SST's flash MCU line, so this is the closest functional replacement.
  • W78E516DDG --: 8051-compatible microcontroller with 64KB flash and similar peripheral set, widely used as a drop-in alternative for SST89E516 series in legacy designs.
  • STC89C52RC-40I-PDIP --: Low-cost 8051-compatible MCU with 8KB flash and 40MHz operation; suitable for less demanding applications where the full 64KB flash of the SST part is not required.
