89H32NT8AG2ZBHL

Overview

The Renesas 89H32NT8AG2ZBHL 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
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication
• Features movable upstream support and on-board DMA capabilities for flexible topology management

Applications

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

Procurement Notes

Verify component authenticity through authorized channels as this specific part number may be subject to obsolescence or end-of-life status. Confirm moisture sensitivity level (MSL 4) handling requirements during storage and assembly. Ensure compatibility with existing PCB footprint designs for the 484-FCBGA package before procurement.

Selection Notes

Select this component when a fixed 32-lane, 8-port PCIe Gen2 configuration is required. Consider alternative models from the same family if different port counts or lane densities are needed. Verify that the 3.3V power requirement aligns with the target system's power delivery infrastructure.

Part Context

This model belongs to the Renesas 89H series of PCIe switches, specifically the 89H32NT8AG2 family. It shares architectural similarities with other variants like the 89H24NT6AG2 and 89H16NT16G2, differing primarily in lane count and port density. These devices are engineered for deterministic low-latency switching in enterprise environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Check for updated generations from Renesas or compatible switches from other manufacturers if this obsolete part is no longer sourced.
