PCI Revision 2.3 compliant

33MHz

5V tolerant PCI signals (except PME#)

Integrated PCI arbiter supports up to seven PCI bus masters

The PCI bus is connected to a PC/104 connector as shown in the section below.

2.5.5 PCI-to-ISA Bridge

A PC/104 expansion connector on the WAFER-8523 facilitates ISA bus expansion. The

PC/104 connector is interfaced to the CPU, through an ITE IT8888F PCI to ISA bridge

single function device. The ITE IT8888F is a bridge between the PCI bus and the ISA bus.

The 32-bit PCI bus interface on the IT8888F is compliant with PCI Specification v2.1 and

supports both PCI Bus Master and Slave. An additional PCI master is interfaced to a

PCI-104 expansion slot. The combination of the PCI-104 and PC/104 slots enables

PC/104-Plus expansion cards to be added to the system.
