The Texas Instruments PCI2250 PCI-to-PCI bridge provides a high performance connection path between two peripheral component interconnect (PCI) buses. Transactions occur between masters on one PCI bus and targets on another PCI bus, and the PCI2250 allows bridged transactions to occur concurrently on both buses. The bridge supports burst-mode transfers to maximize data throughput, and the two bus traffic paths through the bridge act independently.

The PCI2250 bridge is compliant with the PCI Local Bus Specification, and can be used to overcome the electrical loading limits of 10 devices per PCI bus and one PCI device per expansion slot by creating hierarchical buses. The PCI2250 provides two-tier internal arbitration for up to four secondary bus masters and may be implemented with an external secondary PCI bus arbiter.
