Use this divice in a longer cycle than this value. 2. t WC must be longer than this value unless polling techniques or RDY/BUSY are used. This device automatically completes the internal write operation within this value. 3. Next read or write operation can be initiated after t DW if polling techniques or RDY/BUSY are used. 4. Guaranteed by design. TABLE 9. 79LV0408 MODE SELECTION 1, 2 1. X = Don’t care. 2. Refer to the recommended DC operating conditions. PARAMETER CE 3 3.
