Customer specific information*
Year code (last 2 digits of calendar year)
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 characters
for customer specific information.
* 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. For QTP devices, any special marking adders are included in QTP price.
