226 / 240 page  14.0 Device Characteristics (Continued) 226 www.national.com 14.1.4 Power Consumption under Recommended Operating Conditions 14.2 DC CHARACTERISTICS OF PINS, BY I/O BUFFER TYPES The following tables summarize the DC characteristics of all device pins described in the Signal/Pin Connection and De- scription chapter. The characteristics describe the general I/O buffer types defined in Table 1. For exceptions, refer to Sec- tion 14.2.15. The DC characteristics of the system interface meet the PCI2.1 3.3V DC signaling. 14.2.1 Input, CMOS Compatible Symbol: INC 14.2.2 Input, PCI 3.3V Symbol: INPCI Symbol Parameter Conditions Typ Max Unit ICC VDD Average Main Supply Current VIL = 0.5 V, VIH = 2.4 V No Load 32 50 mA ICCLP VDD Quiescent Main Supply Current in Low Power Mode VIL =VSS,VIH =VDD No Load 1.3 1.7 mA IASB AVDD Average Main Supply Current TBD TBD mA ISB VSB Average Main Supply Current VIL = 0.5 V, VIH = 2.4 V No Load 15 mA ISBLP VSB Quiescent Main Supply Current in Low Power Mode VIL =VSS,VIH =VSB V No Load 3mA IBAT VBAT Battery Supply Current VDD,VSB =0V, VBAT =3V 250 nA Symbol Parameter Conditions Min Max Unit VIH Input High Voltage 0.7 VDD 5.5Note 1.
