XIO2200ZGW

Specialized Overview

The XIO2200ZGW is a specialized interface integrated circuit manufactured by Texas Instruments, designed as a PCI Express to PCI translation bridge. It facilitates communication between modern PCI Express systems and legacy PCI hardware. The device operates with dual power supply requirements: a core voltage range of 1.35 V to 1.65 V and an I/O supply of 3 V to 3.6 V. It is housed in a 176-LFBGA package, specifically the 176-BGA MICROSTAR (15x15) configuration, supporting high-density board layouts for industrial and computing applications.

Specialized Feature Summary

• Enables seamless interoperability between PCI Express Gen 1.x architecture and standard PCI bus protocols
• Supports data buffering and logic registration to manage speed differences between CPU and peripheral devices
• Utilizes advanced low-voltage CMOS technology for efficient power management

Specialized Applications

• Industrial control systems requiring legacy PCI expansion
• Embedded computing platforms bridging PCIe and PCI interfaces
• Communication equipment integrating older peripheral cards

Specialized Procurement Notes

Verify the specific suffix ZGW against the official Texas Instruments datasheet to confirm pinout and electrical characteristics. Ensure compatibility with the required 1.35-1.65V core and 3-3.6V I/O supply rails during design integration. Confirm the 176-BGA MICROSTAR package dimensions match the PCB footprint specifications precisely.

Specialized Selection Notes

Select this component when a system requires direct translation between PCI Express and PCI buses without external protocol converters. It is suitable for designs needing compact form factors due to the BGA packaging. Consider the dual voltage supply requirements for power rail planning. This bridge is ideal for maintaining backward compatibility in new hardware designs involving legacy PCI peripherals.

Specialized Part Context

The XIO2200 series from Texas Instruments represents a family of high-performance bridge controllers. The XIO2200ZGW variant specifically targets the 176-ball BGA package format. It belongs to the specialized interface category, addressing the growing need for hybrid bus architectures in mixed-generation electronic systems.

Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternatives, as bridge controllers often have unique pinouts and timing requirements.
