89H32T8G2ZCBLG

Overview

The Renesas 89H32T8G2ZCBLG is a PCI Express Gen2 switch interface IC designed for high-performance system interconnects. It provides 32 lanes and 8 ports, supporting data rates up to 5 Gbps per lane with a total aggregate bandwidth of 256 Gb/s. The device operates on supply voltages of 1 V, 2.5 V, and 3.3 V, functioning within a temperature range of -40°C to +85°C. It utilizes a 484-FCBGA package (23x23 mm) for surface mount installation.

Feature Summary

• Supports PCIe Gen2 standard with non-blocking switching architecture
• Provides partitionable switch architecture for multi-root support
• Includes onboard DMA support and internal buffering for flow control

Applications

• High-performance computing system interconnects
• Storage area network infrastructure
• Telecommunications equipment requiring deterministic latency

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free specifications against the specific manufacturing lot date code. Ensure proper ESD handling procedures are followed during inspection due to moisture sensitivity classification.

Selection Notes

Select this model when 32 lanes and 8 ports are required for PCIe Gen2 applications. Verify that the 484-FCBGA footprint matches the PCB layout constraints. Ensure power delivery networks support the specified 1V, 2.5V, and 3.3V rails simultaneously for correct operation.

Part Context

This component belongs to the IDT/Renesas 89H32T8G2 series of PCIe switches. It serves as a core connectivity solution for expanding PCIe topology in server and storage environments. The part represents a transition from legacy IDT products under the Renesas Electronics portfolio following corporate acquisitions.

Replacement Considerations

Check for pin-compatible alternatives within the same 8-port Gen2 family. Verify if newer generation switches like Gen3 or Gen4 variants offer backward compatibility while meeting bandwidth requirements. Confirm package dimensions remain identical for direct board replacement.
