TSI301-400CE

Specialized Overview

The TSI301-400CE is a high-performance bridge interface chip manufactured by Renesas Electronics Corporation. It provides protocol bridging between HyperTransport and PCI buses. The device supports HyperTransport operation at 400 MHz with an 8-bit data width. On the PCI side, it supports primary bus speeds of 33 MHz or 66 MHz with a 64-bit data path. The component is housed in a 352-SBGA package measuring 35.0 x 35.0 mm with a height of 1.7 mm.

Specialized Feature Summary

• Provides protocol bridging between HyperTransport and PCI interfaces
• Supports 64-bit PCI bus architecture
• Enables connection between systems using different communication standards

Specialized Applications

• System interconnection requiring HyperTransport to PCI conversion
• Backplane connectivity solutions
• Specialized interface circuits for mixed-standard system integration

Specialized Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm exact speed grades and package variants. Ensure compatibility with existing HyperTransport host controllers and PCI target devices before integration. Confirm supply chain authenticity through authorized channels to avoid counterfeit components.

Specialized Selection Notes

Select this component when a design requires direct bridging between a HyperTransport source and a legacy PCI target. Consider the 64-bit PCI bandwidth requirements and the 400 MHz HyperTransport input frequency. Evaluate the SBGA package constraints for PCB layout and thermal management during the design phase.

Specialized Part Context

This part belongs to the TSI301 family of bridge controllers designed by Renesas. These devices facilitate interoperability between high-speed serial links and parallel bus architectures. The family addresses needs in computing systems where distinct interface protocols must communicate seamlessly without software overhead.

Specialized Replacement Considerations

Consult official Renesas substitution lists for verified alternatives. Generic industry equivalents are not confirmed substitutes due to specific pinout and timing differences.
