2732 x voltage

VOLTAGE
------------
What is 2732D and 2732k ?

From check the databook it appears 'D' appears to be just a packaging suffix from AMD and Intel. Otherwise it's just an regular 2732.

Can't find a reference to the 'K' suffix, but I recall having some 2764's with a K suffix which I believe were Mitsubishi parts and programmed just like a 2764.

I had a cheat sheet.. like anything.. no clue where it is when I need it. Correct on the D=25v :)

Anyone can add to the list for other roms and their voltages.

Found 1 oddball 2732JL

PS: I saw 24v which would be 25v for 2732k

Well,

It's simple to program an unknown chip if you do it like this:

Start out with the lowest voltage level for programming (12v) and attempt to program the chip. If it fails, choose the next step up, 21v. If that fails, try 25v.

That is what I did when I made my cheat sheet :)

I know this is an old thread, but I started messing with an EPROM programmer for some EPROM's I want to read, and since I have a spare ROM that's already programmed, figured I'd test that first before doing one I don't want to mess up :) It says M5L 2732K 82211Z Japan. Not sure what brand it is (M5L?) but it definitely has a K suffix. The ones on the board I want to read are 2732D's, so I guess all are 25V.

AH HA ! Found them in a cross reference guide. It is a Mitsubishi part and M5L 2732 equates to 2732, so 25V should be used.

Thanks for the info! Thread resurrection for added info and bookmarking purposes

Some models of EPROMS not in GQ-4x Device menu, but was able to successfully write/verify on:

- Mitsubishi M5L2732K chips with the standard "2732(25V VPP)" Device setting. Did it on -2 Speed and Double-Writes.
- Toshiba TMM2764D chips with the standard "2764(21V VPP)" device setting. Did it on -2 Speed and Double-Writes.
- NEC D27128D chips with the standard "27128(21V VPP)" device setting. Did it on -2 Speed and Double-Writes.
