*Notice: Stresses above those listed under “Maximum ratings” 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 specification 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 specific application, please consult the Total
Endurance Model which may be obtained on Microchip’s BBS or website.
