I need to find a datasheet for the old XC68HC58DW, in order to identify the functionality.
A client of mine needs 2000 of them, but as far as I can tell it's long obsolete since the late 90's.
I'm assuming it is a microcontroller but can't be sure without a datasheet. I'm wondering if a little adapter could be fashioned to allow a modern part to solder directly to the footprint on 2000 original PCB's, with some software updates of course.
