AI Summary

AT45DB321D-SU-2.5 by Microchip Technology: FLASH Memory IC 32Mbit SPI 50 MHz 8-SOIC.

This is the direct next-generation replacement for the obsolete target part, maintaining complete hardware and command set compatibility while offering higher speed and a wider voltage range.

  • Direct next-generation drop-in replacement
  • Same legacy DataFlash pinout and SRAM buffer command set
  • Active lifecycle status with long-term support (estimated to 2034)
  • Single-source proprietary architecture

This is the tube-packaged variant of the direct next-generation replacement, ideal for low-volume assembly or prototyping.

  • Identical specifications to the tape-and-reel version
  • Shipped in protective tubes rather than tape-and-reel
  • Maintains same non-standard DataFlash pin assignments
  • Single-source proprietary architecture

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.

Frequently asked questions

Yes. The Microchip Technology AT45DB321D-SU-2.5 is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
