Looking round, I found these documents.The MCU is older than I am
The Freescale Hibbert website is quite good to find old datasheet and all.

Semiconductors have a shelf life. If yours were not kept in a moist free bag, it would affect their life span. Also, I can only recommend to change to a newer generation if you can. Especially with the free sample programme, you don't have to pay !
