XIO2001PNP

Specialized Overview

The XIO2001PNP is a single-lane PCI Express to PCI translation bridge manufactured by Texas Instruments. It supports up to eight posted and four unposted transactions for downstream traffic, and six posted and four unposted transactions for upstream traffic. The device features a PCIe interface compliant with version 2.0, operating at a maximum clock frequency of 125 MHz with a data rate of 2 Gb/s per lane. It utilizes a 32-bit data bus width and operates within a supply voltage range of 3.3 V or 5 V. The component is housed in an HTQFP-128 package and functions within a temperature range of -40°C to +85°C.

Specialized Feature Summary

• Supports advanced error reporting including extended CRC as defined in the PCI Express base specification.
• Provides simultaneous transaction handling capabilities for both posted and unposted requests in upstream and downstream directions.
• Fully complies with the PCI Express to PCI/PCI-X Bridge Specification version 1.0.

Specialized Applications

• System integration requiring connection between PCI Express host systems and legacy PCI peripheral devices.
• Industrial control systems utilizing mixed-speed bus architectures.
• Embedded computing platforms needing expansion via standard PCI interfaces.

Specialized Procurement Notes

Verify the specific suffix 'PNP' against official datasheets to confirm package type and temperature grade. Ensure firmware requirements are addressed, as software support is necessary for full feature utilization. Confirm RoHS compliance status through manufacturer documentation prior to procurement.

Specialized Selection Notes

Select this component when a single-lane PCIe link is sufficient for bandwidth requirements. Consider the HTQFP-128 package constraints for PCB layout. Evaluate thermal management needs for the specified operating temperature range. Verify compatibility with existing PCI bus signaling levels and timing requirements.

Specialized Part Context

The XIO2001 series serves as a bridge solution for migrating legacy PCI peripherals to modern PCI Express architectures. It allows system designers to maintain backward compatibility while adopting faster interconnect standards. The device simplifies board design by eliminating the need for complex discrete logic solutions.

Specialized Replacement Considerations

The XIO2000A is a documented alternative within the same product family offering similar bridge functionality. Verify pinout compatibility and electrical specifications before substitution. Review updated datasheets for any changes in transaction handling limits or power consumption characteristics.
