89H32NT8AG2ZBHLG

Overview

The Renesas 89H32NT8AG2ZBHLG is a specialized PCI Express switch interface integrated circuit designed for high-performance system interconnect applications. It provides 32 PCIe Gen2 lanes and supports 8 ports, delivering non-blocking throughput with full line rate capabilities regardless of switch loading. The device operates on a 3.3V supply voltage and utilizes a 484-FCBGA package measuring 23x23 mm. Key electrical parameters include a maximum clock frequency of 125 MHz and a data rate of 256 Gb/s. It supports 32/64-bit data bus widths and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Partitionable switch architecture enabling true multi-root support capabilities
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication
• Features movable upstream support and onboard DMA for flexible topology configurations

Applications

• High-performance server system interconnect switching
• Storage area network (SAN) fabric implementations
• Multi-root compute node aggregation systems

Procurement Notes

Verify the specific suffix ZBHLG against current manufacturer documentation to confirm pinout and electrical characteristics. Check component status as this series may be obsolete or end-of-life. Confirm moisture sensitivity level and reflow soldering profiles prior to assembly. Ensure compatibility with existing PCB layout constraints for the 484-FCBGA package dimensions.

Selection Notes

Select this component when 32 lanes and 8 ports are required for PCIe Gen2 connectivity. Compare against the 89H32NT24AG2 if higher port density is needed. Verify that the 3.3V power requirement aligns with the target system design. Consider the FCBGA package size for thermal management and board space allocation during the initial design phase.
