System Management Bus (SMBus 2.0)
The ICH8 contains an SMBus Host interface that allows the processor to communicate
with SMBus slaves. This interface is compatible with most I
commands are implemented.
The ICH8’s SMBus host controller provides a mechanism for the processor to initiate
communications with SMBus peripherals (slaves). Also, the ICH8 supports slave
functionality, including the Host Notify protocol. Hence, the host controller supports
eight command protocols of the SMBus interface (see System Management Bus
(SMBus) Specification, Version 2.0): Quick Command, Send Byte, Receive Byte, Write
Byte/Word, Read Byte/Word, Process Call, Block Read/Write, and Host Notify.
ICH8’s SMBus also implements hardware-based Packet Error Checking for data
robustness and the Address Resolution Protocol (ARP) to dynamically provide address
to all SMBus devices.

The Intel
used to attach different types of codecs, such as audio and modem codecs. The ICH8
Intel HD Audio controller supports up to 4 codecs. The link can operate at either 3.3 V
or 1.5 V.
With the support of multi-channel audio stream, 32-bit sample depth, and sample rate
up to 192 kHz, the Intel HD Audio controller provides audio quality that can deliver CE
levels of audio experience. On the input side, the ICH8 adds support for an array of
microphones.
Intel
The ICH8 integrates four fan speed sensors (four TACH signals) and 3 fan speed
controllers (three Pulse Width Modulator (PWM) signals), which enables monitoring and
controlling up to four fans on the system. With the new implementation of the single-
wire Simple Serial Transport (SST) bus and Platform Environmental Control Interface
(PECI), the ICH8 provides an easy way to connect to SST-based thermal sensors and
access the processor thermal data. In addition, coupled with the new sophisticated
Intel
provides effective thermal and acoustic management for the platform.
