89HPES6T5ZBBC

Specialized Overview

The 89HPES6T5ZBBC is a PCI Express switch interface IC manufactured by Renesas Electronics, belonging to the 89HPES6T5 series. It provides high-performance I/O expansion and switching functions between one upstream port and five downstream ports, or supports peer-to-peer switching between downstream ports. The device features six PCIe Gen2 lanes and six switch ports. It utilizes a CABGA-196 package for surface mount installation. The component is classified as a PCI Interface IC within the Interface ICs subcategory.

Specialized Feature Summary

• Switch architecture optimized for I/O Expansion
• Supports root-to-peripheral (upstream-to-downstream) and peer-to-peer (downstream-to-downstream) data transfers
• Internal buffering and flow control credits optimized for maximum bandwidth and large payloads

Specialized Applications

• PCIe system interconnect switching
• I/O expansion in server platforms
• Peer-to-peer data transfer architectures

Specialized Procurement Notes

Verify the exact suffix of the part number, as the provided model lacks the final character found in common listings like 89HPES6T5ZBBC8. Confirm RoHS compliance status and moisture sensitivity level before procurement. Check for product discontinuance notices from Renesas or IDT, as this family may be obsolete. Ensure the supplier provides valid traceability documentation for the specific manufacturing lot.

Specialized Selection Notes

Select this component when designing systems requiring six PCIe Gen2 lanes with flexible switching capabilities. Compare against other members of the 89HPES6T5 series for pin compatibility and feature variations. Verify that the CABGA-196 package fits the PCB layout constraints. Consider thermal management requirements associated with the internal buffering and switching operations.

Specialized Part Context

This device is part of the 89HPES6T5 family of PCIe switches, originally developed by Integrated Device Technology (IDT) and later acquired by Renesas Electronics. The family includes variants such as 89HPES6T5ZBBCG and 89HPES6T5ZBBCGI. These components are designed for high-performance computing environments requiring deterministic latency and non-blocking throughput across multiple PCIe links.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers include 89HPES6T5ZBBCG and 89HPES6T5ZBBCGI. Verify pinout compatibility and electrical specifications before substitution. Note that these alternatives may have different packaging options or RoHS compliance statuses.
