89H32H8G3YCHLI8

Overview

The 89H32H8G3YCHLI8 is a PCI Express Gen3 system interconnect switch manufactured by Renesas Electronics. It provides 32 lanes and 8 ports, supporting data rates up to 125 MHz per lane for a total bandwidth of 640 Gb/s. The device operates within a temperature range of -40°C to +85°C and utilizes multiple power supply voltages including 1 V, 2.5 V, and 3.3 V. It is housed in a 484-FCBGA package with dimensions of 23x23 mm. This component is designed for high-performance, non-blocking switching applications in server and storage systems.

Feature Summary

• Provides deterministic, non-blocking switching across all ports with full line-rate throughput regardless of switch loading.
• Supports PCIe Gen3 specification with 32 lanes and 8 independent ports for scalable I/O expansion.
• Features advanced link management capabilities including hot-plug support and error reporting mechanisms.

Applications

• High-density server chassis requiring extensive peripheral connectivity
• Storage area networks (SAN) and enterprise storage arrays
• Telecommunications infrastructure equipment

Procurement Notes

Verify the exact suffix CHLI8 against official Renesas documentation to confirm package type and moisture sensitivity level. Check current lifecycle status as this series may be subject to discontinuation notices. Ensure compatibility with existing PCB footprint designs before procurement.

Selection Notes

Select this model when 32 lanes and 8 ports are required for PCIe Gen3 environments. Compare against the 89H32T8G2ZCBLI for Gen2 requirements or the 89H32NT8BG2ZCHLGI8 for alternative packaging options. Confirm voltage domain requirements match the target system design.

Part Context
