Note 1: This parameter is periodically sampled and not 100% tested.

2: tWC begins on the rising edge of CS after a valid write sequence and ends when the internal self-timed write

cycle is complete.

3: This parameter is not tested but guaranteed by characterization. For endurance estimates in a speciﬁc appli-

cation, please consult the Total Endurance Model which can be obtained on our BBS or website.
