89H32H8G3YCHLI

Overview

The 89H32H8G3YCHLI is a PCI Express Gen3 system interconnect switch manufactured by Renesas Electronics. It provides 32 PCIe lanes and 8 switch ports, supporting data rates up to 8 Gbps per lane for a total bandwidth of 256 Gb/s. The device operates with supply voltages of 1 V, 2.5 V, and 3.3 V, and functions within a temperature range of -40°C to +85°C. It utilizes an FCBGA-484 package (23x23 mm) for surface mount installation.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Partitionable switch architecture enabling true multi-root support
• Internal buffering and flow control credits optimized for maximum bandwidth and large payloads

Applications

• High-performance computing systems
• Storage area networks
• Telecommunications infrastructure

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free certification prior to integration. Check for obsolescence notices as this series may be discontinued. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component for applications requiring deterministic latency and non-blocking throughput across multiple traffic flows. Compare against Gen2 variants if backward compatibility is required. Verify pinout compatibility with existing PCB layouts when transitioning from previous generation switches in the same family.

Part Context

This part belongs to the 89H32T8G2/89H32H8G3 series of PCIe switches. It shares architectural similarities with models like the 89H32NT24AG2 but differs in port count and generation speed. The suffix YCHLI indicates specific thermal and packaging variations within the Renesas interface IC portfolio.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider evaluating the 89H32NT24AG2 for higher port density requirements or legacy 89HPES32H8 for Gen1 compatibility, subject to design review.
