89H12NT12G2ZCHLG

Overview

The 89H12NT12G2ZCHLG is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, designed for high-performance system interconnect applications. It functions as a PCI Express switch providing 12 lanes and 12 ports of non-blocking throughput. The device operates with a supply voltage of 3.3V and utilizes a 324-FCBGA package measuring 19x19 mm. It supports PCIe Gen2 specifications and includes features such as internal buffering and flow control credits optimized for large payloads. The component is classified as obsolete status.

Feature Summary

• Provides 12 PCIe Gen2 lanes and 12 switch ports for deterministic system interconnect switching
• Features a non-blocking architecture ensuring full line rate throughput regardless of switch loading
• Supports partitionable switch architecture for true multi-root support
• Includes multiple Nontransparent Bridging (NTB) functions and movable upstream support

Applications

• High Performance System Interconnect
• PCIe Switching Applications
• Multi-root Support Systems

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on secondary market sources or alternative packaging options such as the reel variant 89H12NT12G2ZCHLG8. Confirm RoHS3 compliance and moisture sensitivity level 3 requirements during handling. Cross-reference part number aliases like IDT89H12NT12G2ZCHLG for accurate sourcing.

Selection Notes

Select this component for designs requiring 12-port PCIe Gen2 switching with non-blocking performance. Ensure compatibility with 3.3V power domains and 324-FCBGA footprint constraints. Consider the obsolete status when planning long-term production lifecycles. Verify thermal management capabilities for the FCBGA package in dense system layouts.

Part Context

The 89H12NT12G2ZCHLG belongs to the 89H12N series of PCIe switches from Renesas Electronics. It shares architectural similarities with other models in the family, such as the 89H24NT6AG2 and 89H32NT24AG2, which offer higher lane counts. This specific part number represents a 12-lane configuration within that product line.

Replacement Considerations

Public confirmed substitute part numbers include 89H12NT12G2ZCHLGI8 and 89H12NT12G2ZAHLGI. These variants may differ in temperature grade or packaging type. Verify pinout and electrical specifications against the original datasheet before implementation.
