SNOOZE MODE
SNOOZE MODE is a low-current, “power-down” mode
in which the device is deselected and current is reduced to
ISB2Z. The duration of SNOOZE MODE is dictated by the
length of time ZZ is in a HIGH state. After the device enters
SNOOZE MODE, all inputs except ZZ become gated inputs
and are ignored.
ZZ is an asynchronous, active HIGH input that causes the
device to enter SNOOZE MODE. When ZZ becomes a logic
HIGH, ISB2Z is guaranteed after the setup time tZZ is met. Any
READ or WRITE operation pending when the device enters
SNOOZE MODE is not guaranteed to complete successfully.
Therefore, SNOOZE MODE must not be initiated until valid
pending operations are completed.
