*Notice: Stresses above those listed under “Maximum ratings”
may cause permanent damage to the device. This is a stress rat-
ing only and functional operation of the device at those or any
other conditions above those indicated in the operational listings
of this specication is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.

Note 1: This parameter is tested at Tamb = 25
°C and FCLK = 1 MHz.
2: This parameter is periodically sampled and not 100% tested.
3: This parameter is not tested but guaranteed by characterization. For endurance estimates in a specic
application, please consult the Total Endurance Model which can be obtained on our website.
