Im looking around for some large quanities of AT29C256 chips and all of them have something after the part number and I dont know the difference between them.

example: AT29C256-15JI or AT29C256-15PC

what do they mean?

Trying to burn some turboedit (obd0) and ubderdata chips.

 

nobody replies to my threads

 

Good luck finding a lot since they're out of production, but I don't think it means much, check pgmfi.org, I use old uveproms myself.

 

Define "large quantities".. Besides, you want the 90PC or so units..

I know they are out of production, but there are thousands still in stock on numerous websites and electronic supply stores. The 512s are still in production, and those can also be used. Where do you get your UVeproms?

What does 90PC mean? I would like to know what the part# means.

Thanks.

 

I get my uv eproms on ebay for like 80 cents each from a guy a buy a bunch of other stuff from.

or you can use the 29C replacement; SST 27SF512

 

so does pretty much any 64 x8 eprom chip &gt;256 work?
