SNOOZE MODE
SNOOZE MODE is a low current, “power
down” mode in which the device is deselected and
current is reduced to I
ZZ.
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
The duration of
device to enter SNOOZE MODE. When the ZZ
pin becomes a logic HIGH, I
ZZ
is guaranteed after
the setup time tZZ is met. Any access pending
when entering SNOOZE MODE is not guaranteed
to successfully complete.
MODE must not be initiated until valid pending
operations are completed.
Therefore, SNOOZE
