89H32H8G2ZCBLG

Overview

The Renesas 89H32H8G2ZCBLG is a PCI Express Gen2 switch interface IC designed for high-performance system interconnect applications. It provides 32 lanes and 8 ports, supporting non-blocking switching architecture with full line-rate throughput. The device operates on multiple power supplies including 1V, 2.5V, and 3.3V, with a maximum clock frequency of 125 MHz. It is housed in a 484-FCBGA package measuring 23x23 mm, suitable for surface mount installation. The component supports data rates up to 176 Gb/s and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports partitionable switch architecture enabling true multi-root functionality
• Integrates multiple non-transparent bridging (NTB) functions for isolated domain communication
• Features onboard DMA support and internal buffering for optimized bandwidth utilization

Applications

• High-performance server system interconnects
• Storage area network (SAN) infrastructure
• Telecommunications base station backplanes

Procurement Notes

Verify the specific suffix code against official Renesas documentation to confirm exact package variant and temperature grade. Confirm 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 downstream ports are required for PCIe Gen2 systems. Consider alternative pin-compatible variants if different port counts or thermal grades are needed. Verify voltage domain requirements match the target system design constraints.

Part Context

This component belongs to the Renesas 89H32 family of PCIe switches, which are engineered for scalable system architectures. It serves as a critical node for expanding PCIe connectivity in enterprise and industrial environments requiring deterministic latency and high throughput.

Replacement Considerations

Check for direct pin-to-pin replacements within the same 89H32 series. Evaluate newer generation switches if performance upgrades are acceptable. Verify that any substitute maintains the required 484-FCBGA form factor.
