The PI7C8152A and PI7C8152B (PI7C8152x) are Pericom Semiconductor’s PCI-to-PCI Bridge that are designed to be fully compliant with the 32-bit, 66MHz implementation of the PCI Local Bus Specification, Revision 2.2. The PI7C8152B supports both synchronous and asynchronous bus transactions between devices on the Primary Bus and the Secondary Buses operating up to 66MHz. The PI7C8152A supports synchronous transactions only. In synchronous mode, both buses must operate at the same frequency. The Primary and Secondary Bus can also operate in concurrent mode, resulting in added increase in system performance.
