89H12NT12G2ZAHLG8

Overview

The 89H12NT12G2ZAHLG8 is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 12 lanes and 12 ports with non-blocking architecture for full line-rate throughput. The device operates at a maximum clock frequency of 125 MHz and supports data rates up to 96 Gb/s. Power supply requirements include 1 V, 2.5 V, and 3.3 V rails. It functions within an operating temperature range of -40°C to +85°C. The component is housed in a 324-FCBGA package (19x19 mm) with surface mount installation. It features a 32/64-bit data bus width and holds Moisture Sensitivity Level 3.

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 support with internal buffering and flow control credits

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Enterprise storage systems requiring deterministic latency

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or surplus channels. Ensure RoHS compliance status matches project requirements, as older batches may differ from current standards. Validate authenticity through authorized supply chains due to the discontinued status.

Selection Notes

Select this part for designs requiring 12-port PCIe Gen2 connectivity with low latency. Verify that the 324-FCBGA footprint fits the PCB layout constraints. Confirm power delivery networks can support the 1V, 2.5V, and 3.3V requirements. Consider the MSL 3 rating for reflow soldering profile adjustments during assembly.

Part Context

This device belongs to the 89H12NT12G2 series of PCIe switches. It shares architectural similarities with other models in the family, such as the 89H16NT16G2, but offers a specific 12-lane configuration. The suffix ZAHLG8 indicates specific packaging and environmental compliance attributes defined by Renesas.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements may require design modifications. Consult Renesas technical support for recommended migration paths or newer generation equivalents.
