NOTES:
1. When the internal VccSus1_05 voltage regulator on the ICH7-M/ICH7-U is enabled,
VccSus1_05 is included in the Vcc1_05 rail during the S0 state and in the VccSus3_3 rail
during the S3 - S5 states. There is a negligible change in Vcc1_05 and VccSus3_3 maximum
power consumption when internal VccSus1_05 VR is disabled.
2. When the internal VccSus1_05 voltage regulator on the ICH7-M/ICH7-U is enabled,
VccLAN1_05 is included in the Vcc1_05 rail during the S0 state and in the VccLAN3_3 rail
during the S3 - S5 states. There is a negligible change in Vcc1_05 and VccLAN3_3 maximum
power consumption when internal VccSus1_05 VR is disabled.
3. Integrated VccSus1_05 VR disabled.
4. VccHDA and VccSusHDA at 3.3 V.
5. VccHDA and VccSusHDA at 1.5 V.
6. VccSus3_3 assumes that the 8 high-speed USB 2.0 devices are connected to the ICH7’s root
ports.
7. Icc (RTC) data is estimated with VccRTC at 3.0 V while the system is in a mechanical off (G3)
state at room temperature. Only the G3 state of this rail is shown to provide an estimate of
battery life.
