Part number or part number code
Temperature (I, E)
Year code (last digit of calendar year)
Year code (last 2 digits of calendar year)
Week code (week of January 1 is week ‘01’)
Alphanumeric traceability code (2 characters for small packages)
Pb-free JEDEC designator for Matte Tin (Sn)
Note: For very small packages with no room for the Pb-free JEDEC designator
e3 ^{, the marking will only appear on the outer carton or reel label.}
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.
