89H12NT12G2ZBHLI

Overview

The Renesas Electronics Corporation 89H12NT12G2ZBHLI is a PCI Express Gen2 system interconnect switch providing 12 lanes and 12 ports. It operates with a maximum clock frequency of 125 MHz and supports power supply voltages of 1 V, 2.5 V, and 3.3 V. The device functions within an operating temperature range of -40°C to +85°C. It utilizes a surface-mount installation style in a 324-FCBGA package measuring 19x19 mm. This component is classified as a specialized interface IC designed for high-performance switching applications.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Partionable switch architecture supporting true multi-root configurations
• Supports multiple Nontransparent Bridging (NTB) functions

Applications

• High-performance system interconnect switching
• Multi-root support architectures
• PCIe Gen2 network topologies

Procurement Notes

Verify the current lifecycle status before integration, as this specific part number may be discontinued or restricted. Confirm RoHS compliance requirements against project specifications, noting that some variants lack lead-free certification. Ensure compatibility with existing PCB footprints and thermal management strategies for the FCBGA package. Validate that the required voltage domains (1V, 2.5V, 3.3V) are available on the target board design.

Selection Notes

Select this component when a 12-lane, 12-port PCIe Gen2 switch is required for deterministic data throughput. Consider the industrial temperature grade (-40°C to +85°C) if operation in harsh environments is necessary. Evaluate the need for partitionable architecture features to determine if this model fits the system topology better than simpler bridge solutions. Verify pinout compatibility with existing designs referencing the 324-FCBGA form factor.

Part Context

This device belongs to the 89H12N family of PCIe switches from Renesas Electronics. It shares architectural similarities with other models like the 89H16NT16G2 and 89H24NT24G2, differing primarily in lane and port counts. The ZBHLI suffix indicates specific packaging and environmental characteristics within this product line. Understanding the broader family helps in identifying common configuration tools and reference designs.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific variant are not available in the provided documentation. Due to the discontinued status indicated for similar models, direct replacements may require redesigning the PCB layout. Engineers should consult official Renesas resources for any officially endorsed cross-references or newer generation equivalents.
