*Notice: Stresses above those listed under “Maximum ratings” may
cause permanent damage to the device. This is a stress rating 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 peri-
ods may affect device reliability.

Note 1:
This parameter is tested at Tamb = 25C and FCLK = 1 MHz.
2: Typical program cycle time is 4 ms per word.
3: This parameter is periodically sampled and not 100% tested.
4: This application is not tested but guaranteed by characterization. For endurance estimates in a specic applica-
tion, please consult the Total Endurance Model which can be obtained on our BBS or website.
