89H32NT8AG2ZCHL8

Overview

The Renesas 89H32NT8AG2ZCHL8 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 for multiple traffic flows regardless of switch loading. The device operates with supply voltages of 1V, 2.5V, and 3.3V, ensuring compatibility with various system requirements. It features an internal buffering and flow control credit system optimized for maximum bandwidth and large payloads. The component is housed in a 484-FCBGA package with dimensions of 23x23 mm, suitable for surface mount installation. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Supports partitionable switch architecture for true multi-root support
• Includes onboard DMA support and internal buffering with flow control credits

Applications

• High-performance server system interconnect switching
• Storage area network (SAN) infrastructure
• Enterprise computing platforms requiring multi-root support

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct voltage and packaging specifications. Confirm the component status as obsolete or end-of-life through official Renesas channels before procurement planning. Ensure compatibility with existing PCB footprints for the 484-FCBGA package. Check for any required firmware updates or configuration tools associated with this specific switch variant.

Selection Notes

Select this component when a non-blocking PCIe Gen2 switch with 32 lanes and 8 ports is required for deterministic system interconnect. Consider the 484-FCBGA package size and thermal characteristics during board layout. Verify that the system design supports the necessary 1V, 2.5V, and 3.3V power rails. Evaluate the need for multi-root support and nontransparent bridging functions inherent to this architecture.

Part Context

This part belongs to the Renesas 89H series of PCIe switches, which are designed for high-bandwidth data transfer in enterprise and industrial environments. The 89H32NT8 variant specifically scales down from larger port counts like the 89H32NT24 while maintaining the same lane count and core architecture. It shares functional similarities with other models in the 89H family but differs in port density and specific application targeting.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific obsolete model are not available in the provided documentation. Users should consult Renesas for potential newer generation replacements or equivalent solutions from other manufacturers that match the 32-lane, 8-port PCIe Gen2 specification.
