IC card interface
11. Characteristics
Table 8. Characteristics of IC supply voltage
Tamb = 25 °C; all parameters remain within limits but are only statistically tested for the temperature range; fxtal = 10 MHz; all
currents ï¬owing into the IC are positive; unless otherwise speciï¬ed. Parameters speciï¬ed as a function of
VDD(INTF), VDDI(REG), VDD(INTREGD) or VCC refer to the actual value at the time of measurement.
