PCI2050PDV

Specialized Overview

The Texas Instruments PCI2050PDV is a PCI-to-PCI bridge IC designed to connect two peripheral component interconnect buses. It operates with a maximum clock frequency of 33 MHz and supports 32-bit data bus width. The device utilizes a 208-terminal PDV package and functions within an operating temperature range of 0°C to 70°C. It accepts power supply voltages of 3.3 V and 5 V, featuring universal PCI interfaces compatible with both signaling environments.

Specialized Feature Summary

• Supports concurrent bridged transactions on both primary and secondary buses
• Includes internal two-tier arbitration for up to nine secondary bus masters
• Provides CompactPCI hot-swap extended capability support
• Features independent read and write buffers for each traffic direction

Specialized Applications

• Creating hierarchical buses to overcome electrical loading limits
• Multifunction CompactPCI card implementations
• Adapting single-function cards to meet hot-swap compliance requirements

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm voltage tolerance and temperature grade. Confirm package availability as older revisions may be discontinued or subject to limited stock conditions. Ensure design-in compatibility with target system power supplies before finalizing procurement orders.

Specialized Selection Notes

Select this component when a standard PCI-to-PCI bridge solution is required for systems operating at 33 MHz. Consider the industrial variant if operation below 0°C is necessary. Verify that the 208-terminal QFP package fits the available PCB footprint constraints and thermal management requirements of the host enclosure.

Specialized Part Context

This component belongs to the PCI2050 family of bridge controllers manufactured by Texas Instruments. It serves as a hardware interface layer enabling communication between distinct PCI segments. The device adheres to PCI Local Bus Specification and PCI-to-PCI Bridge Specification standards established during its release period.

Specialized Replacement Considerations

The PCI2050IPDV offers identical functionality but supports an extended temperature range from -40°C to 85°C. Other packages in the series include the GHK and ZHK MicroStar BGA variants.
