TSI310A-133CEY

Specialized Overview

The TSI310A-133CEY is a 64-bit PCI-X bus bridge manufactured by Renesas Electronics Corporation, operating at speeds up to 133 MHz with transfer rates reaching 1 GBps. It connects two electrically separate PCI-X bus domains, supporting concurrent operations on both buses. The device features extensive buffering and prefetching mechanisms for efficient data transfer, including two 4-Kbyte burst read buffers and two 1-Kbyte posted write buffers. It operates in a 3.3V signaling environment and supports synchronous or asynchronous clocking between the primary and secondary interfaces.

Specialized Feature Summary

• Supports full PCI 2.2 backward compatibility while enabling migration to faster PCI-X environments
• Allows concurrent primary and secondary bus operation for optimal system throughput
• Features extensive built-in buffering and prefetching mechanisms for efficient data transfer
• Configurable to support PCI or PCI-X mode on either bus in any combination

Specialized Applications

• Server RAID controllers
• External RAID systems
• Fibre Channel host bus adapters
• Network interface cards
• Embedded computing

Specialized Procurement Notes

Verify the manufacturer designation carefully, as the original datasheet identifies Integrated Device Technology (IDT) as the producer before its acquisition by Renesas. Confirm that the specific suffix 'A-133CEY' matches the required package type and temperature range specifications documented in the official product brief. Ensure compliance with current RoHS directives when sourcing this component.

Specialized Selection Notes

Select this bridge for applications requiring hierarchical expansion of I/O bus structures with high throughput capabilities. Consider the 304-pin HPBGA package constraints during PCB layout design. Evaluate the need for external arbitration if more than six masters are present on the secondary bus, as the internal arbiter has defined limits.

Specialized Part Context

This component belongs to the PCI-X bridge family designed to facilitate the transition from legacy PCI systems to high-speed PCI-X architectures. It serves as a critical interconnect solution for server-grade hardware requiring robust data handling between multiple bus domains. The device maintains compatibility with established PCI standards while offering enhanced performance metrics.

Specialized Replacement Considerations

Direct replacements may include other 64-bit PCI-X bridges from manufacturers such as PLX or Broadcom. Verify pinout compatibility and register-level software compatibility before substitution. Ensure the alternative device supports the same 133 MHz operational frequency and 3.3V I/O requirements.
