It does but the number on your chip does not fit the usual numbering 
schmeme at Microchip at all.

Another scenario would be a custom run at Microchip. AFAIK they offer 
that only for the high-rel market but I may be wrong or it may have been 
different in the past:

http://www.microchip.com/design-centers/rad-hard/asics

What I have also seen, and I don't know if Microchip ever did this, is 
ICs from regular manufacturers packaged in a special fashion for a large 
customer. Then they get a unique number, nobody else knows what is in 
side and nobody talks.
