 AI Summary | AT29C010A-12JI by Microchip Technology: FLASH Memory IC 1Mbit Parallel 120 ns 32-PLCC (13.97x11.43). | Active drop-in replacement from the same manufacturer, offering a faster 70 ns access time and full physical compatibility. Note that the programming command set differs from the original page-write style and requires firmware support for standard JEDEC byte programming if written in-system.
| Active drop-in replacement from a second-source legacy manufacturer, providing ultra-fast 55 ns access speed. It uses the standard AM29F010-style command set which requires system firmware update if the memory is programmed in-circuit.

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 AT29C010A-12JI 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 AT29C010A-12JI are the SST39SF010A-70-4I-NHE (Microchip Technology) and the AS29CF010-55CCIN (Alliance Memory), 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 AT29C010A-12JI 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.
The AT29C010A-12JI (Microchip Technology) is a part in the Memory category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
