89HPES24N3A1ZCBXI

Overview

The Renesas Electronics Corporation 89HPES24N3A1ZCBXI is a PCI Express interface integrated circuit functioning as a high-performance switch. It provides 24 PCIe Gen1 lanes and supports three switch ports, facilitating I/O expansion between upstream and downstream connections. The device utilizes an FCBGA-324 package with surface mount technology. It incorporates internal buffering and flow control credits to optimize bandwidth for large payloads while maintaining low latency and power consumption. This component enables non-blocking data transfer capabilities within system interconnect architectures.

Feature Summary

• Supports root-to-peripheral and peer-to-peer data transfers
• Optimized internal buffering for maximum bandwidth
• Low latency and low power consumption design

Applications

• PCIe I/O expansion systems
• High-performance computing interconnects
• Server and storage switching solutions

Procurement Notes

Verify the exact suffix designation against official Renesas documentation, as the provided model includes an 'I' variant not explicitly detailed in standard public listings. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Check for product discontinuance notices or end-of-life announcements from the manufacturer to ensure long-term supply viability.

Selection Notes

Select this component when designing systems requiring 24 lanes of PCIe Gen1 connectivity across three ports. Ensure the PCB layout supports the FCBGA-324 package dimensions and pitch. Verify that the application environment accommodates the specified thermal characteristics and power requirements associated with high-density PCIe switching operations.

Part Context

This part belongs to the 89HPES series of PCIe switches from Renesas (formerly IDT). It is designed for robust system interconnect applications requiring multiple downstream ports. Similar variants exist with different port counts or lane configurations, such as the 89HPES24NT3ZBBX, which shares similar architectural features but may differ in specific pinouts or packaging options.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided source material. Evaluate other members of the 89HPES family, such as the 89HPES24NT3G2ZCAL8, for potential compatibility. Conduct thorough electrical and mechanical verification before substituting any component.
