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 becomes
logic HIGH, ISB2Z is guaranteed after the time t
ZZI
is met.
SLEEP Mode Electrical Characteristics
(VCC, VCCQ = +3.3V
±
5%)
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.
