ENDURANCE AND DATA RETENTION CAPACITANCE POWER-UP TIMING POWER UP AND DOWN REQUIREMENT The are no restrictions on the sequencing of the bias supplies VCC, V+, and V- provided that all three supplies reach their final values within 1msec of each other. At all times, the voltages on the potentiometer pins must be less than V+ and more than V-. The recall of the wiper position from nonvolatile memory is not in effect until all supplies reach their final value. The VCC ramp rate spec is always in effect. Notes: (5) This parameter is periodically sampled and not 100% tested (6) tPUR and tPUW are the delays required from the time the third (last) power supply (VCC, V+ or V-) is stable until the specific instruction can be issued. These parameters are periodically sampled and not 100% tested. (7) Sample tested only. A.C. TEST CONDITIONS Symbol Parameter Limits Test Conditions Min. Typ. Max. Unit ICC1 VCC supply current (active) 400 µA fSCK = 2MHz, SO = Open, Other Inputs = VSS ICC2 VCC supply current (nonvolatile write) 1mA fSCK = 2MHz, SO = Open, Other Inputs = VSS ISB VCC current (standby) 5 µA SCK = SI = VSS, Addr. = VSS ILI Input leakage current 10 µA VIN = VSS to VCC ILO Output leakage current 10 µA VOUT = VSS to VCC VIH Input HIGH voltage VCC x 0.7 VCC + 0.1 V VIL Input LOW voltage -0.5 VCC x 0.3 V VOL Output LOW voltage 0.4 V IOL = 3mA Parameter Min. Unit Minimum endurance 100,000 Data changes per bit per register Data retention 100 Years Symbol Test Max.
