3 / 15 page U632H64 3 August 15, 2006 STK Control #ML0047 Rev 1.1 b: VCC reference levels throughout this datasheet refer to VCCX if that is where the power supply connection is made, or VCAP if VCCX is con- nected to ground. c: ICC1 and ICC3 are depedent on output loading and cycle rate. The specified values are obtained with outputs unloaded. The current ICC1 is measured for WRITE/READ - ratio of 1/2. ICC2 is the average current required for the duration of the STORE cycle (STORE Cycle Time). d: Bringing E ≥ VIH will not produce standby current levels until any nonvolatile cycle in progress has timed out. See MODE SELECTION table. The current ICC(SB)1 is measured for WRITE/READ - ratio of 1/2. DC Characteristics Symbol Conditions C-Type K-Type Unit Min. Max. Min. Max.
