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 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.
