Microchip part number information
Customer specific information*
Year code (last 2 digits of calender year)
Week code (week of January 1 is week '01’)
Facility code of the plant at which wafer is manufactured.
C = Chandler, Arizona, U.S.A.
S = Tempe, Arizona, U.S.A.
Mask revision number for microcontroller
Assembly code of the plant or country of origin in which
part was assembled.
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 OTP marking consists of Microchip part number, year code, week code,
facility code, mask revision number, and assembly code. For OTP 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.
