What is 2732D and 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.

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 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 upIt 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.
