89H12NT12G2ZBHLGI

Overview

The Renesas 89H12NT12G2ZBHLGI is a PCIe Gen2 system interconnect switch providing 12 lanes and 12 ports. It features a non-blocking architecture with full line-rate throughput for multiple traffic flows. The device supports partitionable switching for multi-root configurations, Nontransparent Bridging (NTB), movable upstream support, and on-board DMA. It operates within a temperature range of -40°C to +85°C using a 324-FCBGA package.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Partitionable switch architecture enabling true multi-root support
• Supports multiple Nontransparent Bridging functions and movable upstream configuration

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Deterministic data flow routing in industrial or enterprise environments

Procurement Notes

Verify the specific suffix ZBHLGI against official Renesas documentation to confirm lead grade and packaging details. Confirm current lifecycle status as obsolete or end-of-life through authorized distributors before procurement planning.

Selection Notes

Select this component when 12-port PCIe Gen2 connectivity with non-blocking performance is required. Ensure design compatibility with 1V, 2.5V, and 3.3V power domains and verify thermal management for the FCBGA package in the target application environment.

Part Context

This part belongs to the 89H12NT12G2 series of PCIe switches from Renesas Electronics. It is functionally similar to other variants in the family but distinguished by its specific package type and commercial/industrial temperature rating suffixes.

Replacement Considerations

Check for direct pin-compatible replacements within the same 89H12NT12G2 series. Verify if newer generation switches offer backward compatibility with Gen2 protocols while providing improved performance metrics.
