Application Scenarios & Design Considerations

80C51 8-bit microcontroller family 4K/128 OTP/ROM/ROMless, expanded I/O

Alternative Part Number

  • P80C451 --: Intel 80C451 is the original CMOS 8051-family microcontroller that Philips second-sourced as the SC80C451; same core, pinout and function, so it is a direct functional replacement.
  • P87C451 --: NXP (formerly Philips) P87C451 is the same 80C451 microcontroller family with on-chip EPROM/ROM options, offering identical architecture and pin compatibility for drop-in use.
  • AT89C51 --: Atmel/Microchip AT89C51 is a widely available 8051-compatible CMOS microcontroller with similar I/O and memory resources, suitable as a practical substitute when the exact 80C451 variant is unavailable.
  • SAB80C515 --: Similar 8051-compatible CMOS microcontroller with comparable peripherals and package options, suitable as a functional substitute.
