89H32H8G3YCHL

Overview

The 89H32H8G3YCHL is a PCI Express Gen3 switch interface IC manufactured by Renesas Electronics. It provides 32 lanes and 8 ports of high-performance, deterministic system interconnect switching. The device features a non-blocking switch architecture optimized for high throughput. It supports multiple non-transparent bridging functions and movable upstream support. The component operates within a temperature range of -40°C to +85°C and utilizes an FCBGA-484 package.

Feature Summary

• Non-blocking switch architecture providing full line rate throughput
• Supports multiple non-transparent bridging (NTB) functions
• Enables true multi-root support through partionable switch architecture

Applications

• High-performance system interconnect partitioning
• Multi-root server configurations
• Data center infrastructure networking

Procurement Notes

Verify the specific suffix YCHL against official Renesas documentation to confirm exact temperature grade and packaging variations. Confirm current lifecycle status as this series may have discontinuation notices. Ensure compatibility with existing PCB footprints for the FCBGA-484 package before procurement.

Selection Notes

Select this component when designing systems requiring 32 PCIe Gen3 lanes with low latency. Compare against the 89H32T8G2ZCBLI if Gen2 speeds are sufficient for lower power requirements. Verify that the 8-port configuration meets the specific topology needs of the target application design.
