89H32NT8AG2ZBHLI8

Overview

The Renesas 89H32NT8AG2ZBHLI8 is a specialized PCI Express switch interface integrated circuit designed for high-performance system interconnect applications. It features a non-blocking architecture with 32 lanes and 8 ports, supporting PCIe Gen2 data rates up to 5.0 GT/s per lane. The device operates on multiple power domains including 1V, 2.5V, and 3.3V supplies. It is housed in a 484-FCBGA package measuring 23x23 mm, suitable for surface mount installation. The component supports a maximum clock frequency of 125 MHz and provides a total data rate of 256 Gb/s. It functions within an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports partitionable switch architecture enabling true multi-root support through independent logical switching zones.
• Integrates multiple non-transparent bridging (NTB) functions to facilitate communication between different PCIe domains.
• Features low latency and low power consumption optimized for maximum bandwidth and large payload transfers.

Applications

• High-performance server system interconnects requiring deterministic switching.
• Storage area networks needing scalable I/O connectivity.
• Communication infrastructure equipment utilizing multi-root configurations.

Procurement Notes

Verify the specific suffix ZBHLI8 against official Renesas documentation to confirm lead-free status and moisture sensitivity level. Confirm current availability as this part number may be subject to discontinuation notices or limited supply conditions. Ensure compatibility with existing PCB footprint designs for the 484-FCBGA package before procurement.

Selection Notes

Select this component when a 32-lane, 8-port PCIe Gen2 switch is required for non-blocking throughput. Consider the 484-FCBGA package size constraints and thermal requirements for the operating environment. Verify that the application benefits from the supported partitionable architecture and NTB capabilities compared to standard switches.
