in our PCB we are using MC8640TVU1067NE processor. but it was obsolete now, in NXP site they mentioned alternative part number is MC8640TVJ1067NE and also mentioned, reason for change is assembly process. what you mean by assembly process change (i.e ic manufacturing process change or PCB assembly process change) and also i want to know is there any other difference between MC8640TVU1067NE and MC8640TVJ1067NE dimension wise (L*B*H and also ball size) and pin configuration wise(one to one pin configuration or not) and functionality wise.
Thanks and Regards,
