* Standard OTP marking consists of Microchip part number, year code, week code,
and traceability code.
** Please visit www.microchip.com/Pbfree for the latest information on Pb-free
conversion.
Note: For very small packages with no room for the Pb-free JEDEC designator
, the marking will only appear on the outer carton or reel label.
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.
