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.
