89H12NT12G2ZCHLI

Overview

The 89H12NT12G2ZCHLI is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, designed as a PCI Express switch. It provides 12 PCIe Gen2 lanes and 12 switch ports within a non-blocking architecture optimized for high-performance system interconnect partitioning. The device supports true multi-root configurations through its partionable switch architecture and includes multiple Nontransparent Bridging (NTB) functions. It operates with supply voltages of 1 V, 2.5 V, and 3.3 V, featuring a maximum clock frequency of 125 MHz and a data rate of 96 Gb/s. The component is housed in a 324-FCBGA package measuring 19x19 mm, suitable for surface mount installation.

Feature Summary

• Non-blocking switch architecture ensuring full line-rate throughput for multiple traffic flows regardless of switch loading.
• Partionable switch design enabling true multi-root support and flexible system configuration.
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream capabilities.
• Integrated on-board DMA support with internal buffering and flow control credits optimized for large payloads.

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Industrial temperature grade applications

Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturing channels. Buyers must confirm the specific suffix variations and lead times carefully, as standard production runs are no longer active. Cross-referencing with equivalent replacement parts from the same family is recommended for new designs.

Selection Notes

Select this model when a 12-lane, 12-port PCIe Gen2 switch is required for deterministic system interconnect. Ensure compatibility with 1 V, 2.5 V, and 3.3 V power domains. Verify that the 324-FCBGA footprint fits the PCB layout constraints. Consider the industrial temperature range if operating conditions exceed commercial limits. Confirm that the non-transparent bridging features align with the system's multi-root requirements.

Part Context

The 89H12NT12G2 series belongs to Renesas' portfolio of PCI Express system interconnect switches. This specific variant utilizes the ZCHL suffix to denote package and environmental specifications within the FCBGA form factor. It shares architectural similarities with other models like the 89H24NT6AG2 and 89H32NT24AG2 but offers a distinct lane-to-port ratio tailored for specific scaling needs in high-density computing environments.

Replacement Considerations

Publicly confirmed substitute part numbers include 89H12NT12G2ZCHLG and 89H12NT12G2ZCHLGI8. These variants share the same core functionality but may differ in packaging type (tray vs. reel) or lead-free status. Verify pinout compatibility and electrical specifications before substitution.
