Title: Seems like I bricked 95160
Post by: borderm3 on December 06, 2021, 02:18:16 PM
Hi All,

I think I bricked a 95160 trying to write it with a clip without desoldering.  Yes, lazy...

I have since tried reading it with an adapter and by soldering to adapter directly in zif socket.  Using a vvdi prog.  I pulled a ST 93C86 out of an MS43 and was able to read and write and read that just fine.  Therefore, I believe my vvdi prog is operational.

Will this 95160 chip work properly?

So I got M95160-DRMN3TP/K from digikey.

I am able to read it and write a blank bin but it anytime I try to write a non blank bin I get 'Write Error(00)'.  Does anyone know if perhaps these are write protected or something?  I suspect my VVDI Prog should be able to write any ST 95160 not just the exact ones that came in the ECU's?

TIA

If I do a verify, I get a 'check failure'.  Perhaps the checksum is different for these two chips?  In over my head here, anyway to correct it to make it work?

Do you tried to access this eeprom while on the pcb?
