Note 1: Not 100% tested.
2: The combined TSP and VHYS specifications are due to new Schmitt Trigger inputs, which provide improved
noise spike suppression. This eliminates the need for a TI specification for standard operation.
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
