1. Use this device 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.
