b: V_CC reference levels throughout this datasheet refer to V_CCX if that is where the power supply connection is made, or V_CAP if V_CCX is con-
nected to ground.
c: I_CC1 and I_CC3 are depedent 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 (STORE Cycle Time).
d: Bringing E ≥ V_IH will not produce standby current levels until any nonvolatile cycle in progress has timed out. See MODE SELECTION
table.The current I_CC(SB)1 is measured for WRITE/READ - ratio of 1/2.
