Any idea how to read N70005FWCHCA ?

Is an Intel chip, have tried reading as a 28F512 with no luck.

Any ideas?

thanks,
Jonathan

Never mind, try 28F010.

Hey Anniel

No luck, get the same thing - when I try to read it just 00 00 00 etc.

Any others I can try?

I am using the PLCC32 to DIP 32 adapter, and as noted have the chip pin #1 in GQ4X at pin #5 per the picture.

No, get ID fails too.

Maybe another chip I need to send to ZLM...

I recall reading there was something special about this chip and reading it in a eeprom, but I haven't been able to find that...

Pins are clean? No conformal coating residue?

Flipped pinout? Verify on your PCB for power pins if it matches the 28F010 Datasheet.

No conformal coating residue, chip works in socketed ECU ok, just not GQ 4X.

Will check the power pins on PCB with a meter and report back if they match the same as the 28F010 datasheet.

Yes, the pinout could be different.
