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 rev#, 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.
