*Standard device marking consists of Microchip part number, year code, week code, and traceability code. For

device marking beyond this, certain price adders apply. Please check with your Microchip Sales Office.

Legend: XX...X Part number or part number code

T Temperature (I, E)

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’)

NNN 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

, 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.
