Need help with chip ID

Postby darkman5001 » Mon Mar 13, 2023 5:13 am

I am looking for some help in identifying these chips. They are all from P04 PCMs. Thank you in advance.

Anything with 466 DE means its under license by Delco Electronics (who are number 466), and they might be custom, or might be off the shelf, but either way its unlikely you'll find any public references to the numbers on them. You'll need to compare other pcms where a little more is known, and go by their location on the PCB and maybe if you can trace any tracks to somewhere that'll give some clues. The platform should be pretty similar to the P01, similar function of chips etc.
