89HPES24T6ZCBXI

Overview

The 89HPES24T6ZCBXI is a PCI Express switch manufactured by Renesas Electronics, designed for high-performance I/O expansion. It features 24 PCIe Gen1 lanes and six switch ports, supporting both root-to-peripheral and peer-to-peer data transfers. The device utilizes an FCBGA-324 package with surface mount installation. Internal buffering and flow control credits are optimized for maximum bandwidth and large payloads, ensuring low latency and power consumption. This component serves as a system interconnect solution for expanding peripheral connectivity in complex electronic architectures.

Feature Summary

• Provides non-blocking switching architecture optimized for high-performance system interconnect applications
• Supports partitionable switch architecture enabling true multi-root support capabilities
• Integrates multiple Nontransparent Bridging (NTB) functions for isolated domain communication
• Features movable upstream support and on-board DMA support for flexible system design

Applications

• High-performance server I/O expansion chassis
• Storage area network (SAN) controller interconnects
• Industrial automation systems requiring deterministic switching
• Telecommunications infrastructure equipment

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation to ensure compatibility with specific thermal and environmental requirements. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Check for product discontinuance notices or obsolescence status, as availability may be limited. Ensure sourcing from authorized distributors to guarantee authenticity and traceability of the semiconductor components.

Selection Notes

Select this component when designing systems requiring 24 lanes of PCIe Gen1 connectivity with six independent ports. Consider the FCBGA-324 package constraints for PCB layout and thermal management. Evaluate the need for Nontransparent Bridging and multi-root support features inherent to this series. Compare against newer generation switches if future-proofing or higher bandwidth standards like Gen2 or Gen3 are required for the target application.

Part Context

This part belongs to the 89HPES24 family of PCIe switches, which includes variants such as 89HPES24T6G2ZCALI8 and 89HPES24NT3ZBBX. These devices share common architectural foundations but differ in lane counts, port configurations, and supported PCIe generations. The 89HPES24T6ZCBXI specifically addresses Gen1 requirements within this portfolio, offering a balance of performance and integration for legacy or cost-sensitive high-bandwidth applications.
