89HPES24N3A1ZCBXG8

Overview

The Renesas Electronics Corporation 89HPES24N3A1ZCBXG8 is a PCI Express interface integrated circuit designed for high-performance I/O expansion. It functions as a 24-lane, 3-port switch supporting PCIe Gen1 specifications. The device provides switching capabilities between one upstream port and two downstream ports, or enables peer-to-peer communication between downstream ports. It incorporates internal buffering and flow control credits to optimize bandwidth utilization for large payloads while maintaining low latency and power consumption.

Feature Summary

• Supports root-to-peripheral and peer-to-peer data transfer architectures
• Optimized internal buffering and flow control for maximum bandwidth efficiency
• Low latency design with reduced power consumption characteristics

Applications

• High-performance I/O expansion systems
• Server infrastructure requiring multiple peripheral connections
• Storage area network (SAN) interconnect solutions

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the specific suffix indicates lead-free composition. Validate package integrity upon receipt, as moisture sensitivity levels require proper handling procedures during storage and assembly to prevent damage.

Selection Notes

Select this component when designing systems requiring 24 lanes of PCIe Gen1 connectivity across three ports. Ensure the application supports the specific FCBGA package dimensions and pinout configuration. Verify that the system architecture aligns with the non-blocking switch capabilities and does not require Gen2 speeds or additional port counts found in other series variants.

Part Context

This part belongs to the IDT/Renesas 89HPES24N3 family of PCIe switches. It shares architectural similarities with the 89HPES24T3G2 series but differs in generation support and packaging options. The ZCBXG8 suffix denotes specific manufacturing lot and lead-free attributes within the broader product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider the 89HPES24T3G2ZCAL8 for Gen2 upgrades, though functional differences exist. Evaluate cross-reference availability through official Renesas obsolescence notices for direct replacements.
