89H32NT8AG2ZCHLGI

Overview

The 89H32NT8AG2ZCHLGI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 lanes and 8 ports of high-performance, deterministic switching with non-blocking architecture. The device supports multiple voltage supplies including 1V, 2.5V, and 3.3V. It operates within a temperature range of -40°C to +85°C. The component is housed in a 484-FCBGA package measuring 23x23 mm. Maximum clock frequency is 125 MHz. This specific part number is listed as obsolete or end-of-life.

Feature Summary

• Non-blocking switch architecture optimized for high performance system interconnect
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple Nontransparent Bridging (NTB) functions
• Includes onboard DMA support and internal buffering with flow control credits

Applications

• High-performance server system interconnects
• Storage area network (SAN) infrastructure
• Telecommunications base stations requiring low latency
• Industrial automation control systems

Procurement Notes

Verify current availability status as the component may be discontinued. Check for end-of-life notices from Renesas. Confirm package integrity and moisture sensitivity level before handling. Ensure compatibility with existing PCB layouts using the 484-FCBGA footprint. Consult authorized distributors for last-time buy options if production continuity is required.

Selection Notes

Select this model when 32 lanes and 8 ports are required for PCIe Gen2 applications. Consider partitionable architecture needs for multi-root support. Verify voltage requirements match the 1V, 2.5V, and 3.3V supply rails. Ensure thermal management suits the -40°C to +85°C operating range. Evaluate NTB functionality requirements for isolated domain communication.

Part Context

This component belongs to the IDT 89H series of PCIe switches. It is part of a family that includes variants with different port counts such as the 89H32NT24 and 89H24NT6. The suffix ZCHLGI indicates specific packaging and environmental compliance details. These devices were designed to replace older generation interconnect solutions with higher bandwidth capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The component is marked as obsolete. Designers should evaluate newer Renesas PCIe switch families or alternative vendors offering equivalent lane and port configurations with active manufacturing status.
