What's Inside?
System Board Description
SPI (Serial Peripheral Interface)
The Serial Peripheral Interface is a 4-pin interface that provides a lower
cost alternative for system BIOS flash than the Firmware Hub and LPC
Bus.
The ICH8M supports up to two SPI devices with speeds of up to 33Mhz.
One SPI interface is dedicated to U55, the WS5A BIOS.
SATA (Serial Attached ATA)
The ICH8M supports the Serial ATA Specification, Revision 2.5 and
supports independent DMA operation on up to three ports with data
transfer rates of up to 3.0 Gb/s. Each SATA channel consists of a transmit
and receive pair.
The System Board includes a SATA data connector and custom power
connector to support a single SATA 2 1/2" HDD or SSD. The optional kit is
supplied with one SATA SSD, Mounting Plate, SATA Data Cable and
custom Power Cable.

PCI Bus

The ICH8M PCI interface provides a 33 MHz, Revision 2.3
implementation. The ICH8M integrates up to four external PCI Bus
masters. One PCI interface is used to support the Mini-PCI connector
CN12. The Mini-PCI connector supports a WiFi card, and modem.

Ethernet

The ICH8M integrates a Gigabit Ethernet Controller that is compatible
with the Intel 82867 Gigabit LAN Platform Connect Device.
The ICH8M integrated GbE controller supports multi-speed operation of
10/100/1000 Mb/s. The interface can operate in full duplex at all supported
speeds or half-duplex at 10/100 Mb/s and complies with the IEEE 802.3x
Flow Control Specification.

HD Audio

The ICH8M contains a High Definition Audio (HDA) controller that
communicates with an external codec over the Intel High Definition Audio
serial link. The HDA protocol is controller synchronous, based on a
24MHz Bit Clock sent by the ICH8M HD Audio controller.
The input and output streams, including command and PCM data, are
isochronous with a 48Khz frame rate. The ICH8M implements four DMA
output engines and four DMA input engines. The output DMA engines
move digital data from system memory to the D-A converter in the codec.
The input DMA engines move digital data from the A-D converter in the
codec to system memory.
