SNOOZE MODE
mode in which the device is deselected and current is
reduced to I
dictated by the length of time the ZZ pin is in a HIGH
state. After the device enters SNOOZE MODE, all in-
puts except ZZ become gated inputs and are ignored.
NOTE: 1. This parameter is sampled.

DESCRIPTION
Current during SNOOZE MODE
ZZ active to input ignored
ZZ inactive to input sampled
ZZ active to snooze current
ZZ inactive to exit snooze current

that causes the device to enter SNOOZE MODE. When
the ZZ pin becomes a logic HIGH, I

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.
The ZZ pin is an asynchronous, active HIGH input
