CC1
and I
CC3
are dependent on output loading and cycle rate. The specified values are obtained with outputs unloaded
The current I
CC1
is measured for WRITE/READ - ratio of 1/2.
I
CC2
is the average current required for the duration of the STORE cycle (t
STORE
).
Bringing E

IH
will not produce standby current levels until any nonvolatile cycle in progress has timed out.
The current I
