EPROM L2732HS

[Dylan]

Im after an eprom for a non automotive application. Anyone know of a supplier?
A quick Google wasn't real successfull. Maybe an alternative is available? 24 pin it is.
I would like to be able to read it with my GQ4X and write to a new one.

Any help appreciated.

cant the gq-4x identify it?

Haven't got it home yet. I'll look it up tonight on there software.
Is it possible to stuff an eprom from reading it wrong?

probably just fit a 28 pin 27c128 in its place out of a vn memcal lots of people used to when messing with gaming consoles and other car ecu's that run 24 pin be pretty easy to fit a socket and wire 28pin to work as normal

It's already socketed for a 24 pin so might not be too easy? Im worried about stuffing it while trying to read it.
It's irreplaceable.

I made some 2732 adapter boards a while ago for some really old ecus, they use a 27sf512 flash and give 16 banks.
I'm sure I've still got a few boards somewhere...

I'd be interested in a photo. If this goes ahead about 6 from memory I'd need.

I made these for replacing 27C32 EPROMs in Bosch LE2 ignition ECUs. The 4 jumpers select one of 16 banks from the stacked bin.
That made for a pretty flexible ignition setup, 16 sets of maps to choose between

Well that looks impressive. I know very little about eproms.
Delcowizzid mentioned above about using a 27C128.
Would it be as easy as sitting that in the 24 pin socket and reading the old 24 pin and then writing that to the 28 pin?

Any idea what access speed this thing needs to be?

You have a TMS2732A, which came in speeds as fast as 170ns.

The only thing I can find is this :

NTE2732A (200ns)
