Unknown IC

[Electro]

Hi,
I have IC 04041803 manufactured by GI. Package is DIL 40.
There is no datasheet or any info about.

Anyone help?

Thanks in advance!

That looks like a "House Number", in which case ECG/TCG may have a
replacement for it. Otherwise you have to hope the manufacturer supports
whatever this is out of and can supply you with a replacement.

Of course you could always send it to a company that specializes in
reverse engineering and they can take the top off and figure out what it
is...however that is usually insanely expensive if the item is a toaster
or microwave oven.

No, as the other buy pointed out, it's a house number. Even if it's a
renumbered generic part, chances are good it's a microcontroller (GI made
what might be the predecssors of the PIC controllers), and once you've got
that, chances are good it has the actual software inside in ROM. So if
there's a generic version, it won't do you any good since you don't have
the software.

The more pins an IC has, the more likely it's specialized.

The information you left out was where this IC was. If it was just lying
by itself, there's no way it's worth any effort. If it's inside something
and it actually needs replacing, then nobody will be able to help without
information on what it was in, what the device did.
