Chip ID needed.

[W Gray]

Greetings.

Hope this message finds each of you well.

Several years ago I purchased a chip at a hamfest that at the time seemed
promising, but need some information, please.

It's got a small rectangular window in which appears to be two rows of
contacts, seven or eight on a side. The manufacturer is Sharp and the ID
is: PTO 32A.

Thanks,
W Gray

FWIW, it's a PT032A (zero, not oh).

A window would suggest an EPROM, but a pin count of only 16 (?) would
seem rather low.

Sounds like a relay ?

I'm a bit surprised anyone replied to this. If you did not receive a
datasheet or any other information on the part, then for what
application could it possibly have seemed promising, except perhaps
jewelry?

I think it is an image sensor of some sort, possibly from a handy-
scanner, but that is an educated guess.

If you post photos of the part someone might be able to make a better
guess at what it is, but do you really want to waste the effort to
build something around an exquisitely obscure part of which you will
never see another sample?
