89H12NT12G2ZCHL8

Overview

The 89H12NT12G2ZCHL8 is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, designed for high-performance system interconnect applications. It functions as a PCIe Gen2 switch providing 12 lanes and 12 ports with non-blocking architecture. The device operates at a maximum clock frequency of 125 MHz and supports data rates up to 96 Gb/s. It accommodates 32-bit or 64-bit data bus widths and requires supply voltages of 1 V, 2.5 V, and 3.3 V. The component is housed in a 324-FCBGA package measuring 19x19 mm, suitable for surface mount installation.

Feature Summary

• Provides deterministic system interconnect switching with full line rate throughput across all ports regardless of loading conditions.
• Supports partitionable switch architecture enabling true multi-root functionality and multiple Nontransparent Bridging (NTB) functions.
• Features onboard DMA support and internal buffering optimized for large payloads and maximum bandwidth efficiency.

Applications

• High-performance system interconnect switching
• PCI Express Gen2 network infrastructure
• Multi-root server architectures

Procurement Notes

This component is officially classified as obsolete by the manufacturer. Verification of availability should focus on secondary market distributors rather than direct procurement from Renesas. Buyers must confirm the specific suffix variant matches their hardware requirements, as packaging types such as tape and reel may differ from legacy tray versions. Compliance with RoHS3 standards is documented for this part number.

Selection Notes

Engineers selecting this component should verify compatibility with PCIe Gen2 specifications and ensure the 324-FCBGA footprint fits the target PCB layout. The requirement for multiple voltage rails (1V, 2.5V, 3.3V) must be addressed in the power design. Due to the obsolete status, alternative sourcing strategies or redesign considerations for newer generations may be necessary for long-term production viability.

Part Context

The 89H12NT12G2ZCHL8 belongs to the 89H12N series of PCI Express switches. It shares architectural similarities with other models like the 89H12NT12G2ZCHLG but differs in packaging configuration. This specific suffix indicates a tape and reel carrier type, distinct from the tray-packaged variants within the same functional family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The datasheet references the 89H12NT12G2ZCHLG as a related variant with different packaging. No direct cross-reference substitutes are listed.
