89H12NT12G2ZAHLI8

Overview

The Renesas Electronics Corporation 89H12NT12G2ZAHLI8 is a PCI Express interface integrated circuit functioning as a high-performance system interconnect switch. It provides twelve PCIe Gen2 lanes and twelve switch ports, delivering non-blocking throughput for multiple traffic flows regardless of switch loading. The device operates with power supply voltages of 1 V, 2.5 V, and 3.3 V. It supports a maximum clock frequency of 125 MHz and achieves a data rate of 96 Gb/s. The component utilizes a 324-FCBGA package with dimensions of 19x19 mm and is designed for surface mount installation. It functions within an operating temperature range from -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Support for 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
• Storage area network infrastructure

Procurement Notes

Verify the specific suffix ZBHLI8 against official documentation to confirm lead-free status and moisture sensitivity level. Confirm RoHS compliance requirements as some variants in this series may not meet current standards. Check for end-of-life notices or product change notifications that may affect long-term availability. Ensure compatibility with existing PCB footprints for the 324-FCBGA package before procurement.

Selection Notes

Select this component when twelve PCIe Gen2 lanes are required for deterministic switching. Consider the partitionable architecture if multi-root support is necessary for the design. Evaluate the 324-FCBGA package constraints against board space limitations. Verify thermal management capabilities for the industrial temperature grade if operating near the upper limit.
