JUNE 2008 REVISION 1.1
INTRODUCTION
Product Description
The PI7C8154B is Pericom Semiconductor’s PCI-to-PCI Bridge, designed to be fully compliant
with the 64-bit, 66MHz implementation of the PCI Local Bus Specification, Revision 2.2. The
PI7C8154B supports synchronous and asynchronous bus transactions between devices on the
Primary Bus and the Secondary Buses operating up to 66MHz. For the PI7C8154B-80, the
Secondary Bus supports up to 80MHz operation. The primary and secondary buses can also
operate in concurrent mode, resulting in added increase in system performance.
