AI Summary

AT89C51CC01CA-RLTUM by Microchip Technology: 80C51 AT89C CAN Microcontroller IC 8-Bit 40MHz 32KB (32K x 8) FLASH 44-VQFP (10x10).

This is the direct drop-in replacement recommended by the manufacturer. It has identical technical specifications, package size, pin assignments, and ships with the same default CAN bootloader. It is in an active lifecycle stage.

  • Pin-compatible, true drop-in replacement with identical package, dimensions, and pinout
  • Active lifecycle status ensuring continuous supply
  • Maintains the same factory-programmed CAN bootloader out of the box

This is an active sibling variant that is physically identical to the target part. However, it ships with a default UART bootloader instead of a CAN bootloader, which may require adaptations in initial manufacturing programming. Once your custom firmware is flashed, the electrical and runtime behavior is completely identical.

  • Direct physical drop-in with identical package, layout, and pinout
  • Active lifecycle status with robust stock availability
  • Identical 80C51 core, memory, peripherals, and electrical ratings
  • Factory bootloader defaults to UART instead of CAN, requiring adjustment to initial flashing protocols if CAN-based factory programming is relied upon.

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
