FFF CompatibilityFeatures the exact same JEDEC PLCC-32 pin mapping, with Pin 1 as NC.Identical physical footprint and 32-lead PLCC shape.Fully compatible 2Mbit parallel flash functionality with a significantly higher speed rating of 55ns.The SST39VF020-70-4C-NHE is housed in the identical PLCC-32 package and features a matching pin configuration. Pin 1 is No Connection (NC), which perfectly matches the Don't Connect (DC) pinout of the original AT49LV002NT.The mechanical package dimensions, J-lead PLCC-32 footprint, and surface-mount configuration match the original device perfectly.This device matches the 2Mbit (256K x 8) density and parallel interface. It meets or exceeds the original performance with a faster 70ns read speed and a broader supply voltage range.
AI Summary

AT49LV002NT-90JC by Microchip Technology: NOR Flash 256K x 8 (2M bit).

The LF version specifically matches the 3.0V to 3.6V supply range of the original while boosting the read speed substantially to 55ns in a direct drop-in package.

  • Even faster read access time (55 ns vs 90 ns)
  • Direct pin-compatible drop-in replacement (Pin 1 is NC)
  • Identical core voltage supply range (3.0V to 3.6V)

This is the most direct commercial-grade drop-in replacement. It offers perfect physical and pinout compatibility while delivering faster access speeds and a wider supply voltage range.

  • Direct pin-compatible drop-in replacement (Pin 1 is NC)
  • Faster read access time (70 ns vs 90 ns)
  • Wider operating voltage range (2.7V to 3.6V covers original 3.0V to 3.6V)

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.
