| FFF Compatibility | Pins are mapped identically, allowing it to mount directly onto the existing PCB land pattern.Uses the identical JEDEC MS-016 AE PLCC-32 package dimensions.The read access time is slower (70 ns) compared to the original device's 55 ns. | Pins are mapped identically, allowing it to mount directly onto the existing PCB land pattern.Uses the identical JEDEC MS-016 AE PLCC-32 package dimensions.It is restricted to a narrower 3.0V to 3.6V supply range and commercial temperature range (0°C to +70°C). | ||
 AI Summary | AT49BV001ANT-55JU by Microchip Technology: FLASH Memory IC 1Mbit Parallel 55 ns 32-PLCC (13.97x11.43). | This is the closest industrial-grade alternative, offering a direct pin-to-pin drop-in replacement. It operates over the exact same 2.7V to 3.6V supply range and industrial temperature window, though it features a slightly slower 70 ns access time.
| This alternative is ideal for applications requiring the original 55 ns timing. However, it requires a minimum supply voltage of 3.0V and is limited to commercial temperature ranges.

You searched one part. Parter watches your whole BOM.
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.
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.
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 AT49BV001ANT-55JU 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.
The closest qualified second sources for the Microchip Technology AT49BV001ANT-55JU are the SST39VF010-70-4I-NHE (Microchip Technology) and the SST39LF010-55-4C-NHE (Microchip Technology), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the AT49BV001ANT-55JU are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
