Power and Ground Signals

Name Description

Vcc3_3

3.3 V supply for core well I/O buffers. This power may be shut off in S3, S4, S5 or
G3 states.

Vcc1_5

1.5 V supply for core well logic. This power may be shut off in S3, S4, S5 or G3
states.

VccHI

1.5 V supply for Hub Interface 1.5 logic.
1.8 V supply for Hub Interface 1.0 logic.
This power may be shut off in S3, S4, S5 or G3 states.

V5REF

Reference for 5 V tolerance on core well inputs. This power may be shut off in S3,
S4, S5 or G3 states.

HIREF

Analog Input. Expected voltages are:
• 0.9 V for HI 1.0 (Normal Hub Interface) Series Termination
• 350 mV for HI 1.5 (Enhanced Hub Interface) Parallel Termination
This power is shut off in S3, S4, S5, and G3 states.

VccSus3_3

3.3 V supply for resume well I/O buffers. This power is not expected to be shut off
unless the system is unplugged.

VccSus1_5

1.5 V supply for resume well logic. This power is not expected to be shut off
unless the system is unplugged.

V5REF_Sus

Reference for 5 V tolerance on resume well inputs. This power is not expected to
be shut off unless the system is unplugged.

VccRTC

3.3 V (can drop to 2.0 V min. in G3 state) supply for the RTC well. This power is
not expected to be shut off unless the RTC battery is removed or completely
drained.

NOTE:

Implementations should not attempt to clear CMOS by using a jumper to

pull VccRTC low. Clearing CMOS in an Intel® ICH4-based platform can be done
by using a jumper on RTCRST# or GPI, or using SAFEMODE strap.

VccPLL

1.5 V supply for core well logic. This signal is used for the USB PLL. This power
may
be shut off in S3, S4, S5, or G3 states.

VBIAS

RTC well bias voltage. The DC reference voltage applied to this pin sets a current
that is mirrored throughout the oscillator and buffer circuitry.

V_CPU_IO

Powered by the same supply as the processor I/O voltage. This supply is used to
drive the processor interface outputs.

Vss

Grounds.

6.3 Intel 82801DB I/O Controller Hub 4 (ICH4)
