89H32H8G3YCHLG

Overview

The 89H32H8G3YCHLG is a PCIe Gen3 switch manufactured by Renesas Electronics. It provides 32 lanes and 8 ports within a 484-FCBGA package measuring 23x23 mm. The device supports data rates up to 8 Gbps per lane, achieving a total bandwidth of 256 Gb/s. It operates with supply voltages of 1 V, 2.5 V, and 3.3 V across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture ensuring full line-rate throughput for all traffic flows
• Supports partitionable switch architecture for multi-root functionality
• Includes onboard DMA support and internal buffering with flow control credits

Applications

• High-performance system interconnect switching
• Server and storage networking infrastructure
• Telecommunications equipment requiring deterministic latency

Procurement Notes

Verify the specific suffix YCHLG against official Renesas documentation to confirm voltage and temperature grades. Confirm current availability status as distribution channels may list obsolete or limited stock items. Ensure compatibility with existing PCB footprints and power delivery networks before procurement.

Selection Notes

Select this component when a high-port-count PCIe Gen3 switch is required for non-blocking data transfer. Compare against similar models like the 89H32NT series for feature parity. Verify that the 484-ball FCBGA package fits the target board design constraints and thermal management requirements.

Part Context

This part belongs to the IDT 89H32 family of PCIe switches, originally developed by Integrated Device Technology before its acquisition by Renesas. These devices are designed for demanding computing and communications applications requiring high bandwidth and low latency interconnect solutions.

Replacement Considerations

Check for direct pin-compatible substitutes such as the 89H32NT8BG2ZCHLGI8. Verify functional equivalence regarding lane count and port configuration. Consult manufacturer notices for any recommended obsolescence alternatives.
