89H32NT8BG2ZAHLI8

Overview

The 89H32NT8BG2ZAHLI8 is a PCI Express switch interface IC manufactured by Renesas Electronics. It provides 32 lanes and 8 ports, supporting PCIe Gen2 specifications with a maximum clock frequency of 125 MHz. The device operates on supply voltages of 1 V, 2.5 V, and 3.3 V. It features a data bus width of 32/64 bits and a total data rate of 256 Gb/s. The component is housed in an FCBGA-484 package (23x23 mm) designed for surface mount installation. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Supports true multi-root functionality through partionable switch architecture
• Includes internal buffering and flow control credits to maximize bandwidth and handle large payloads

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area network infrastructure

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and it may not be sold in all regions. Verify current stock status with authorized distributors before design finalization. Consider lifecycle management strategies due to discontinuation status.

Selection Notes

Select this model when a non-blocking PCIe Gen2 switch with 8 ports and 32 lanes is required. Ensure compatibility with 1V, 2.5V, and 3.3V power domains. The FCBGA-484 package requires appropriate PCB layout considerations for thermal management and signal integrity at 125 MHz clock speeds.

Part Context

This part belongs to the 89H32NT8 series of PCIe switches from Renesas (formerly IDT). It shares architectural similarities with variants like 89H32NT8AG2ZAHLI8 but differs in specific suffix designations which may indicate packaging or revision differences. It is distinct from the older 89HPES32H8 series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements are not explicitly listed. Designers should evaluate newer generations of PCIe switches from Renesas or other vendors for long-term supply stability.
