• Description: 2-port Pci-to-pci Bridge
• Manufacturer: Pericom Semiconductor Corporation

INTRODUCTION
Product Description
The PI7C8154A 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
PI7C8154A supports synchronous bus transactions between devices on the Primary Bus and the
Secondary Buses operating up to 66MHz. The primary and secondary buses can also operate in
concurrent mode, resulting in added increase in system performance.
