Can't identify old MCU - M68EVB908Q

AlexMeyer — Thu, 30 Jul 2009 21:40:26 GMT

I've purchased a M68EVB908Q development kit years ago and never used it.

According to the included documentation, it has a MC68HC908QT processor plugged in,

but the chip itself has the inscriptions:

PCQ4C3L69J

ZRHZ4

0233

I couldn't find the meaning of this code anywhere in this site.

Can anyone explain how I determine exactly what processor it is ?

Thank you very much.

Hello,

Try this, it could be a start for an answer....

Hi,

So the PC says its an early pre-production one and the mask set 3L69J matching the errata shows that it is a QT2.
