Sleep Mode
The ZZ input pin is an asynchronous input. Asserting ZZ plac-
es the SRAM in a power conservation
“
sleep
”
mode. Two clock
cycles are required to enter into or exit from this
“
sleep
”
mode.
While in this mode, data integrity is guaranteed. Accesses
pending when entering the
“
sleep
”
mode are not considered
valid nor is the completion of the operation guaranteed. The
device must be deselected prior to entering the
“
sleep
”
mode.
