* Standard PIC

device marking consists of Microchip part number, year code, week code, and traceability

code. For PIC 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.

Legend: XX...X Customer-specific information

Y Year code (last digit of calendar year)

YY Year code (last 2 digits of calendar year)

Pb-free JEDEC designator for Matte Tin (Sn)

* This package is Pb-free. The Pb-free JEDEC designator ( )

can be found on the outer packaging for this package.

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.
