Note 1: This parameter is tested at T
AMB = 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 on Microchip’s website:
