Advance Information Datasheet
Figure 8. Example V5REF Sequencing Circuit
Table 29. 82801E C-ICH Power Planes
V5REF is the reference voltage for 5 V tolerance on inputs to the 82801E C-ICH. V5REF must
power up before or simultaneous to Vcc3_3, and must power down after or simultaneous to
Vcc3_3. Refer to Figure 8 for an example circuit schematic that may be used to ensure proper
V5REF sequencing.

Vcc3_3: Powered by the main power supply.
Vcc1_8: Powered by the main power supply.
V_CPU_IO: Powered by the main power supply via processor voltage regulator.
VccRTC: When other power is available (from the main supply), external diode
coupling will provide power to reduce the drain on the RTC battery. Assumed to operate
from 3.3 V down to 2.0 V.
