89H24NT6AG2ZAHLG8

Overview

The Renesas 89H24NT6AG2ZAHLG8 is a PCIe Gen2 system interconnect switch providing 24 lanes and 6 ports. It operates at 5.0 GT/s with a total switching capacity of 192 Gbps. The device utilizes a non-blocking architecture to support multiple simultaneous traffic flows across all ports. It features a 484-FCBGA package (23x23 mm) and supports 3.3V supply voltage. The component includes internal buffering, flow control credits, and on-board DMA support for optimized bandwidth handling.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput for multiple concurrent traffic flows regardless of switch loading conditions.
• Partitionable switch design enabling true multi-root support through dynamic reconfiguration of downstream, upstream, and non-transparent bridge ports.
• Integrated Non-Transparent Bridging (NTB) functions allowing communication between switch partitions, external PCIe domains, or CPUs.

Applications

• High-performance server systems requiring deterministic system interconnect switching.
• Storage area networks needing low-latency data transfer capabilities.
• Communication infrastructure equipment utilizing multi-root I/O virtualization.

Procurement Notes

Verify the specific suffix ZAHLG8 against official Renesas documentation to confirm lead-free status and industrial temperature grade. Confirm current manufacturing status as this model family has faced discontinuation notices. Ensure compatibility with existing PCB footprints and power delivery requirements before procurement.

Selection Notes

Select this component when designing systems requiring 24 PCIe Gen2 lanes with flexible port partitioning. Consider the 484-FCBGA package size constraints during layout. Evaluate thermal management needs due to high-density switching operations. Verify that the required number of Non-Transparent Bridge endpoints fits within the six-port limit.

Part Context

This part belongs to the IDT 89HPES series of PCIe switches acquired by Renesas. It serves as a high-performance interconnect solution for complex multi-host environments. The device replaces older generations by offering enhanced partitioning and NTB capabilities compared to standard non-partitionable switches in the same form factor.

Replacement Considerations

Public records indicate the 89H24NT6AG2ZBHLGI8 as a similar variant within the same package type. Verify if the specific suffix changes affect temperature range or lead content. Cross-reference with the 89H32NT24AG2 for higher lane count requirements, noting the pinout differences.
