I'm working with a team on repairing some old electronics units, and one of the parts that we came across was ATI's microcontroller part number 216T9NGBGA13FHG . From paperwork on a similar part number, we were able to decode the meaning of each digit except for the last one, and we need to know this so that we can justify substituting part number "216T9NGBGA13FH" into the unit (same part number minus the G) because it's less than 10% of the cost and much more widely available.
Is anyone able to help us out with this question?
