89H12NT12G2ZBHLGI8

Overview

The 89H12NT12G2ZBHLGI8 is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 12 lanes and 12 ports with non-blocking architecture for high-performance deterministic switching. The device supports multiple Nontransparent Bridging (NTB) functions, movable upstream support, and on-board DMA. It operates within an industrial temperature range of -40°C to +85°C using a 324-FCBGA package. Key electrical parameters include a maximum clock frequency of 125 MHz, data rates up to 96 Gb/s, and supply voltages of 1 V, 2.5 V, and 3.3 V.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple Nontransparent Bridging (NTB) functions
• On-board DMA and internal buffering for large payload optimization

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Industrial temperature applications requiring robust connectivity

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability should focus on remaining stock from authorized distributors or secondary market suppliers. Confirm RoHS compliance status and moisture sensitivity level (MSL) prior to procurement, as these specifications may vary based on production date and specific packaging variants.

Selection Notes

Select this part for designs requiring 12-port PCIe Gen2 switching with industrial temperature ratings. Ensure the PCB layout accommodates the 324-FCBGA package dimensions. Verify that the power delivery network supports the required 1 V, 2.5 V, and 3.3 V rails. Consider the end-of-life status when planning long-term product lifecycles.

Part Context

The 89H12NT12G2 series belongs to Renesas' PCIe Gen2 switch family, designed for deterministic system interconnect. This specific variant includes industrial temperature grading and lead-free construction. It shares architectural similarities with other models in the 89H12NT series but differs in thermal rating and packaging suffixes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative solutions require manual evaluation of pin compatibility and functional equivalence.
