4.1 Package Marking Information
Legend: XX...X Part number or part number code

Y Year code (last digit of calendar year)
YY Year code (last 2 digits of calendar year)
WW Week code (week of January 1 is week ‘01’)

RoHS-compliant JEDEC designator for Matte Tin (Sn)
Note: For very small packages with no room for the RoHS-compliant JEDEC

Note: In the event the full Microchip part number cannot be marked on one line, it will
be carried over to the next line, thus limiting the number of available
characters for customer-specific information.
