No. Sym. Characteristic Min. Max. Units Test Conditions Note 1: This parameter is periodically sampled and not 100% tested. 2: 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 our web site: www.microchip.com. 3: TWC begins on the rising edge of CS after a valid write sequence and ends when the internal write cycle is complete.
