INTRODUCTION
PRODUCT DESCRIPTION
The PI7C7300A is Pericom Semiconductor’s second-generation PCI-PCI Bridge. It is
designed to be fully compliant with the 32-bit, 66MHz implementation of the
PCI Local
Bus Specification, Revision 2.2.
The PI7C7300A supports only synchronous bus
transactions between devices on the Primary Bus running at 33MHz to 66MHz and the
Secondary Buses operating at either 33MHz or 66MHz. The Primary and Secondary
Buses can also operate in concurrent mode, resulting in added increase in system
performance. Concurrent bus operation off-loads and isolates unnecessary traffic from
the Primary Bus; thereby enabling a master and a target device on the same Secondary
PCI Bus to communicate even while the Primary Bus is busy. In addition, the Secondary
Buses have load balancing capability, allowing faster devices to be isolated away from
slower devices. Among the other features supported by the PI7C7300A are: support for
up to 15 devices on the Secondary Buses, Compact PCI Hot Swap (PICMG 2.1, R1.0)
Friendly
Support and Dual Addressing Cycle.
