Notes: 1. t
and t
are defined as the time at which the outputs achieve the open circuit conditions and are
no longer driven.
2. Use this device in longer cycle than this value.
3. t
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.
4. Next read or write operation can be initiated after t
DW
if polling techniques or RDY/
Busy
are used.
5. This parameter is sampled and not 100% tested.
6. A7 to A16 are page addresses and must be same within the page write operation.
7. See AC read characteristics.
