Note 1:
This parameter is tested at Tamb = 25
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.
