XIO2213AZAY

Specialized Overview

The XIO2213AZAY is a Texas Instruments integrated circuit functioning as a PCI Express to IEEE 1394b OHCI Host Controller. It integrates a three-port PHY to facilitate data transfer between PCIe and FireWire interfaces. The device operates within an industrial temperature range of -40°C to +85°C. It utilizes a 167-pin NFBGA package for surface-mount installation, designed for high-density board layouts in embedded systems requiring interface bridging capabilities.

Specialized Feature Summary

• Integrates a three-port physical layer (PHY) for direct connection to IEEE 1394b devices
• Provides native host controller functionality compliant with the Open Host Controller Interface (OHCI) specification
• Supports bidirectional protocol translation between PCI Express and IEEE 1394b standards

Specialized Applications

• Industrial automation systems requiring legacy FireWire peripheral connectivity
• Embedded computing platforms needing PCIe expansion via 1394b ports
• Data acquisition hardware utilizing high-speed serial bus interfaces

Specialized Procurement Notes

Verify the specific suffix 'AZAY' against the manufacturer's official ordering guide to confirm package type and temperature grade. Ensure compatibility with the system's PCIe lane configuration and power supply requirements before procurement. Cross-reference the document revision date to ensure access to the latest errata and design guidelines.

Specialized Selection Notes

Select this component when a single-chip solution is required to bridge PCIe hosts with multiple IEEE 1394b endpoints. Consider the 167-pin NFBGA package constraints during PCB layout planning. Evaluate thermal dissipation needs given the industrial operating range and integrated PHY power consumption characteristics.

Specialized Part Context

This part belongs to the XIO2213 family of interface controllers from Texas Instruments. It serves as a specialized bridge chip, distinct from general-purpose logic or standard interface transceivers. The device addresses the niche requirement of maintaining legacy 1394b connectivity in modern PCIe-based architectures without external protocol converters.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify if newer revisions of the XIO2213 series offer pin-compatible alternatives or updated packaging options directly from the manufacturer.
