89H32NT24AG2ZBHLI8

Overview

The Renesas 89H32NT24AG2ZBHLI8 is a PCIe Gen2 system interconnect switch providing 32 lanes and 24 ports. It features a non-blocking architecture optimized for high-performance data transfer, supporting full line-rate throughput across multiple traffic flows regardless of switch loading. The device operates with supply voltages of 1V, 2.5V, and 3.3V, and supports a maximum clock frequency of 125 MHz. It utilizes a 484-FCBGA package (23x23 mm) and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture ensuring deterministic system interconnect switching
• Partitionable switch design 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 server system interconnects
• Storage area network (SAN) infrastructure
• Multi-root compute node configurations

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm moisture sensitivity level (MSL 4) handling requirements during storage and assembly. Ensure compatibility with existing PCB layouts regarding the 484-FCBGA footprint and voltage domain specifications before integration into new designs.

Selection Notes

Select this component when requiring a high-port-count PCIe Gen2 switch with partitioning capabilities. Compare against alternative models in the 89H series based on specific lane-to-port ratios and thermal management needs. Verify that the 484-ball BGA package fits within the mechanical constraints of the target application board.
