Note 1:
This parameter is tested at TA = 25°C and FCLK = 1 MHz.
2:
This parameter is periodically sampled and not 100% tested.
3:
This parameter is not tested but ensured by characterization. For endurance estimates in a specific
application, please consult the Total Endurance Model which can be obtained from Microchip’s web site
