SLEEP Mode
SLEEP Mode is a low current “Power-down” mode in
which the device is deselected and current is reduced to
I
SB2Z
. This duration of SLEEP Mode is dictated by the
length of time the ZZ is in a HIGH state. After entering
SLEEP Mode, all inputs except ZZ become disabled and
all outputs go to High-Z.
The ZZ pin is asynchronous, active high input that causes
the device to enter SLEEP Mode. When the ZZ pin
SLEEP Mode Electrical Characteristics
(VCC, VCCQ = +3.3V
±
5%)
becomes logic HIGH, ISB2Z is guaranteed after the time
t
ZZI
is met, Any operation pending when entering SLEEP
Mode is not guaranteed to successfully complete.
Therefore, SLEEP Mode (READ or WRITE) must not be
initiated until valid pending operations are completed.
Similarly, when exiting SLEEP Mode during t
RZZ
, only a
DESELECT or READ cycle should be given while the
SRAM is transitioning out of SLEEP Mode.
