SNOOZE MODE
SNOOZE MODE is a low-current, “power-down”
mode in which the device is deselected and current is
reduced to I
SB
2
Z
. The duration of SNOOZE MODE is
dictated by the length of time the ZZ pin is in a HIGH
state. After the device enters SNOOZE MODE, all inputs
except ZZ become disabled and all outputs go to
High-Z.
The ZZ pin is an asynchronous, active HIGH input
that causes the device to enter SNOOZE MODE.
When the ZZ pin becomes a logic HIGH, I
SB
2
Z
is guaran-
teed after the time
t
ZZI 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. Similarly, when
exiting SNOOZE MODE during
t
RZZ, only a DESELECT
or READ cycle should be given.
