ICH8ME Low Pin Count (LPC) Interface

The ICH8ME LPC interface complies with the LPC 1.1 specifications. The LPC bus from

the ICH7 is connected to the ITE IT8712F Super I/O chipset. For more detailed

information please refer to Section 2.8.2.

ICH8ME PCI Interface

The PCI bus on the ICH8ME is compliant with the PCI Revision 2.3 implementation. Some

of the features of the PCI interface are listed below.

PCI Revision 2.3 compliant

33 MHz

5V tolerant PCI signals (except PME#)

Integrated PCI arbiter supports up to seven PCI bus masters

2.6.5.1 ITE IT8888G PCI-to-ISA Bridge

The ICH8ME is interfaced to an ITE IT8888G PCI-to-ISA bridge through the PCI bus. The

ITE IT8888G PCI-to-ISA bridge is then connected to an ISA edge connector on the bottom

of the PCISA-9652 thereby enabling legacy ISA card expansion on the backplane. The

PCI to ISA bridge is shown in Figure 2-9.

NOTE:

The ICH8ME integrated in PCISA-9652 supports non-DMA ISA

devices.
