We are using the MC9S08AW32 model for our products (for the last 4 years) and recently we have faced some failures on field. After examination of the faulty boards, we have found out that the VDD and VSS pins were short circuited internally.

We also inspected the chips direct from the tray (taking all the antistatic precautions) and we found that the VDD and VSS pins were already short circuited on a few chips.

We also have a few problems with the A/D module and the FLL module (not locking up).


Do you have faced similar problems with the specific family?


Thanks in advance.
