down” mode in which the device is deselected and
the current is reduced to I
ZZ.
The duration of
SNOOZE MODE is dictated by the length of time
the ZZ pin is in a HIGH state. After entering
SNOOZE MODE, the clock and all other inputs
are ignored.
The ZZ pin (pin 63) is an asynchronous ,
SNOOZE MODE ELECTRICAL CHARACTERISTICS
SNOOZE MODE is a low current, “power
active HIGH input that causes the device to enter
SNOOZE MODE. When the ZZ pin becomes a
logic HIGH, I
ZZ
is guaranteed after the setup time
t
ZZ is met. Any access pending when entering
SNOOZE MODE is not guaranteed to successfully
complete. Therefore, SNOOZE MODE must not
be initiated until valid pending operations are
completed.
