XIO2000AIZZZ

Specialized Overview

The XIO2000AIZZZ is an integrated PCI Express-to-PCI bridge manufactured by Texas Instruments. It facilitates data transfer between a PCI Express root complex and legacy PCI peripherals. The device operates within a temperature range of -40°C to 85°C. It utilizes a 176-pin Thin Quad Flatpack (TQFP) package with a 0.5 mm pitch. The component supports PCI bus compatibility and includes features for system integration.

Specialized Feature Summary

• Provides bridging functionality between PCI Express and standard PCI architectures
• Supports operation in extended industrial temperature environments
• Utilizes a compact surface-mount package design

Specialized Applications

• Industrial control systems requiring legacy PCI interface connectivity
• Data acquisition hardware integrating modern PCIe buses with older peripheral cards
• Embedded computing platforms necessitating mixed-bus architecture support

Specialized Procurement Notes

Verify the specific suffix AIZZZ against official Texas Instruments documentation to confirm pinout, package dimensions, and operating temperature range. Ensure compliance with RoHS directives and lead-free manufacturing standards as specified in the current datasheet. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and supply chain integrity.

Specialized Selection Notes

Select this component when a single-chip solution is required to connect PCI Express hosts to PCI slave devices. Consider the TQFP package constraints for PCB layout and thermal management. Evaluate the need for extended temperature ratings compared to commercial grade alternatives. Confirm signal integrity requirements for the specific PCI and PCIe speeds supported by the bridge controller.

Specialized Part Context

This bridge chip belongs to the XIO2000 family designed to simplify system design by eliminating discrete logic components. It serves as a critical interconnect element in hybrid systems where newer processors must communicate with established PCI-based expansion cards or sensors without requiring full platform redesign.

Specialized Replacement Considerations

Consult Texas Instruments application notes for verified alternative bridge controllers. Verify electrical compatibility and pin assignments before substituting with other PCI Express-to-PCI bridge ICs from different manufacturers.
