89H12NT12G2ZCHLG8

Overview

The 89H12NT12G2ZCHLG8 is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, functioning as a PCI Express switch. It provides twelve PCIe Gen2 lanes and twelve switch ports within a non-blocking architecture designed for high-performance system interconnect partitioning. The device supports true multi-root capabilities through its partitionable design and includes multiple Nontransparent Bridging (NTB) functions. Key electrical specifications include support for 1V, 2.5V, and 3.3V power supplies, with a maximum clock frequency of 125 MHz and a data rate of 96 Gb/s. It operates within a temperature range of -40°C to +85°C and utilizes a 324-FCBGA package measuring 19x19 mm.

Feature Summary

• Non-blocking switch architecture optimized for deterministic system interconnect switching across multiple traffic flows.
• Partitionable switch architecture enabling true multi-root support and flexible system configuration.
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream configurations.
• Includes on-board DMA support with internal buffering and flow control credits optimized for large payloads.

Applications

• High-performance system interconnect partitioning
• Multi-root server architectures
• PCIe switch implementations requiring low latency

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the discontinued status of this part number. Confirm that the specific suffix '8' indicates reel packaging rather than tray packaging when sourcing replacements. Ensure compliance with RoHS3 standards and check for any relevant Product Change Notices affecting assembly sites or marking changes prior to procurement.

Selection Notes

Select this component for designs requiring a 12-lane, 12-port PCIe Gen2 switch with non-blocking throughput. Consider the 324-FCBGA footprint and 19x19mm dimensions during PCB layout. Verify thermal management requirements for the -40°C to +85°C operating range. Evaluate compatibility with existing system power rails supporting 1V, 2.5V, and 3.3V inputs.

Part Context

This part belongs to the 89H12N series of PCIe switches from Renesas, formerly IDT. It shares architectural similarities with other models in the family but is distinguished by its specific lane count and port configuration. The '8' suffix typically denotes tape and reel packaging, differentiating it from tray-packaged variants like the ZCHLG model.

Replacement Considerations

Public confirmed substitute part numbers include 89H12NT12G2ZCHLGI8. Verify pinout and electrical compatibility before substitution. Other family members may offer similar functionality but require validation against specific design constraints.
