PCI2250PGFG4

Specialized Overview

The PCI2250PGFG4 is a 32-bit, 33 MHz PCI-to-PCI bridge controller manufactured by Texas Instruments. It facilitates connectivity between two PCI buses, enabling expansion and resource management in systems requiring multiple PCI segments. The device supports standard PCI specifications for configuration space access and interrupt handling. It is housed in a plastic package designed for surface-mount technology applications. This component serves as an interface solution for integrating additional PCI peripherals or subsystems within a host architecture.

Specialized Feature Summary

• Provides bridging functionality between two independent PCI bus segments
• Supports 32-bit data width and 33 MHz clock frequency operation
• Manages configuration space and interrupt routing between connected buses

Specialized Applications

• Systems requiring expansion of PCI bus topology
• Industrial control systems with multiple PCI peripheral cards
• Legacy computer architectures needing PCI segmentation

Specialized Procurement Notes

Verify the specific suffix 'G4' against official Texas Instruments documentation to confirm lead-free status and RoHS compliance details. Confirm availability status as the base model PCI2250 has been noted as obsolete in some distributor listings. Ensure the package type matches the design requirements before ordering.

Specialized Selection Notes

Select this component when a dedicated hardware bridge is required between two PCI domains rather than software-based solutions. Consider the pin count and package constraints during PCB layout. Verify that the system voltage levels are compatible with the PCI specification supported by this bridge controller.

Specialized Part Context

This part belongs to the PCI2250 family of PCI-to-PCI bridge controllers. The 'PGF' indicates the package style, while 'G4' typically denotes a lead-free and RoHS-compliant variant produced by Texas Instruments. It is distinct from other bridge chips like the PCI2150 which may offer different feature sets or performance levels.

Specialized Replacement Considerations

Check for direct replacements such as the PCI2250 without the G4 suffix if lead-free certification is not strictly required for the current application phase. Evaluate alternative bridge controllers from Texas Instruments or other vendors if the PCI2250 series is discontinued.
