FFF CompatibilityPins 31 and 32 are swapped (SST39VF020 has Pin 31 as VDD and Pin 32 as WE#, while AT49BV002ANT has Pin 31 as WE and Pin 32 as VCC). It requires a board layout modification to route these pins correctly.Both devices are housed in a standard 32-lead PLCC package.Both parts are 2Mbit parallel flash memories with a 70 ns access time and a 2.7V to 3.6V supply. Note that the SST39VF020 uses a uniform 4KB sector architecture, which requires software/driver adjustments compared to the target's non-uniform boot block architecture.Pins 31 and 32 are swapped (VDD and WE#), requiring minor board routing changes.Both devices use the standard 32-lead PLCC package.Narrower voltage supply range (3.0V to 3.6V vs 2.7V to 3.6V) and narrower temperature range (Commercial 0°C to +70°C vs Industrial -40°C to +85°C). Software adjustments are also required for the uniform 4KB sector structure.
AI Summary

AT49BV002ANT-70JU by Microchip Technology: FLASH Memory IC 2Mbit Parallel 70 ns 32-PLCC (13.97x11.43).

An active 2.7V parallel flash alternative that matches the density, package, voltage, and temperature range of the obsolete target part. However, it requires minor board layout adjustments because Pins 31 and 32 are swapped, and software modifications are necessary due to the uniform sector erase architecture.

  • Active lifecycle status
  • Same PLCC-32 (J-Lead) physical package footprint
  • Matches the 2Mbit (256K x 8) density and 70 ns speed
  • Pins 31 (VDD) and 32 (WE#) are swapped compared to the target's pinout
  • Uniform 4KB sector erase architecture requires software/driver modifications to replace the target's boot block memory organization

A faster 55 ns alternative operating in a narrower 3.0V to 3.6V voltage window and commercial temperature range. It shares the same 32-lead PLCC package but has swapped Pins 31 and 32, requiring PCB trace routing updates alongside software adaptation for its uniform sector architecture.

  • Active lifecycle status
  • Same PLCC-32 package footprint
  • Faster access time (55 ns vs 70 ns)
  • Narrower voltage supply range (3.0V to 3.6V)
  • Narrower commercial operating temperature range (0°C to +70°C)

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.
