SNOOZE MODE
SNOOZE MODE is a low-current, “power-down” mode
in which the device is deselected and current is reduced to
I
SB2Z
. 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 dis-
abled 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
SB2Z
is guaranteed after the time t
ZZI
is met. Any READ or WRITE operation pending when the
device enters SNOOZE MODE is not guaranteed to complete
sucessfully. 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.
