NOTES:
1. Due to the integrated 1.05 V voltage regulator on the ICH7, VccSus1_05 is included in the
Vcc1_05 rail during the S0–S1 states and in the VccSus3_3 rail during the S3–S5 states.
2. VccSus3_3 assumes that the 8 high-speed USB 2.0 devices are connected to the ICH7’s root
ports.
3. 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.
