SNOOZE MODE

SNOOZE MODE is a low current, “power

down” mode in which the device is deselected and

current is reduced to IZZ. The duration of

SNOOZE MODE is dictated by the length of time

the ZZ pin is in a HIGH state. After entering

SNOOZE MODE, the clock and all other inputs

are ignored. The ZZ pin (pin 64) is an

asynchronous, active HIGH input that causes the

device to enter SNOOZE MODE. When the ZZ

pin becomes a logic HIGH, IZZ is guaranteed after

the setup time tZZ is met. Any access pending

when entering SNOOZE MODE is not guaranteed

to successfully complete. Therefore, SNOOZE

MODE must not be initiated until valid pending

operations are completed.
