XIO2001IPNP

Specialized Overview

The XIO2001IPNP is a single-function PCI Express to PCI translation bridge manufactured by Texas Instruments. It complies with the PCI Express to PCI/PCI-X Bridge Specification 1.0 and supports a PCI Express x1 link operating at 250 MB/s per direction, adhering to PCI Express Base Specification 2.0. The device features a 32-bit data bus width and operates within a temperature range of -40°C to +85°C. It utilizes an HTQFP-128 surface-mount package and requires 3.3V or 5V power supplies. The bridge supports up to eight posted transactions and four unposted transactions for downstream traffic, while upstream traffic supports six posted and four unposted transactions.

Specialized Feature Summary

• Provides a migration path from conventional PCI to PCI Express technology
• Supports advanced error reporting including extended CRC (ECRC)
• Reduces board space requirements compared to traditional solutions

Specialized Applications

• System migration from PCI to PCI Express architectures
• High-throughput interface bridging in computing systems
• Embedded designs requiring compact PCIe-to-PCI conversion

Specialized Procurement Notes

Verify the specific suffix IPNP against the official datasheet to confirm pinout and package configuration. Ensure compatibility with system voltage requirements of 3.3V or 5V. Confirm that firmware or software updates are available if utilizing advanced error reporting features like ECRC. Check for RoHS compliance status as indicated in the manufacturer's documentation.

Specialized Selection Notes

Select this component when a single-function bridge is required for migrating legacy PCI peripherals to modern PCI Express hosts. Consider the HTQFP-128 package size constraints during PCB layout. Evaluate thermal performance within the specified -40°C to +85°C operating range. Verify that the host system supports the necessary transaction depths for optimal throughput.

Specialized Part Context

The XIO2001 series serves as a bridge solution for transitioning between PCI and PCI Express standards. The XIO2001IPNP variant specifically denotes the industrial-grade temperature range and HTQFP-128 packaging. It is part of Texas Instruments' portfolio aimed at simplifying system upgrades without redesigning entire motherboard architectures.

Specialized Replacement Considerations

The XIO2000A is a documented similar component offering comparable PCI Express to PCI translation capabilities. Verify pin compatibility and electrical specifications before substitution.
