Write start time
Notes: 1. t
is 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 is 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 is used.
5. A16 through A14 are page addresses and these addresses are latched at the first falling edge of
WE
.
6. A16 through A14 are page addresses and these addresses are latched at the first falling edge of
CE
.
7. See AC read Characteristics.
