*Notice: Stresses above those listed under âMaximum ratingsâ may
cause permanent damage to the device. This is a stress rating only and
functional operation of the device at those or any other conditions
above those indicated in the operational listings of this speciï¬cation is
not implied. Exposure to maximum rating conditions for extended peri-
ods may affect device reliability.

This parameter is tested at Tamb = 25°C and FCLK = 1 MHz.
This parameter is periodically sampled and not 100% tested.
This application is not tested but guaranteed by characterization. For endurance estimates in a speciï¬c application, please consult the Total
Endurance Model which may be obtained on Microchipâs BBS or website.
