INTRODUCTION
Product Description
The PI7C8140A is Pericom Semiconductor’s PCI-to-PCI Bridge, designed to be fully compliant with
the 32-bit, 66MHz implementation of the PCI Local Bus Specification, Revision 2.2. The PI7C8140A
supports synchronous bus transactions between devices on the Primary Bus and the Secondary Buses
operating up to 66MHz. Both primary and secondary buses must operate at the same frequency. The
primary and secondary buses can also operate in concurrent mode, resulting in added increase in system
performance.
