Customer specific information*

Week code (week of January 1 is week ‘01’)
Alphanumeric traceability code
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 char-
acters for customer specific information.
* Standard marking consists of Microchip part number, year code, week code, facility code, mask rev#,
and assembly code. For marking beyond this, certain price adders apply. Please check with your
Microchip Sales Office. For SQTP devices, any special marking adders are included in SQTP price.
