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 ZZ is in a HIGH state. After
the device enters SNOOZE MODE, all inputs except ZZ
become gated inputs and are ignored.
ZZ is an asynchronous, active HIGH input that causes
the device to enter SNOOZE MODE. When ZZ becomes
a logic HIGH, I
SB
2
Z
is guaranteed after the setup time
t
ZZ
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.
