89H24NT6AG2ZCHL8

Overview

The Renesas 89H24NT6AG2ZCHL8 is a discontinued PCI Express Gen2 system interconnect switch providing 24 lanes and 6 ports. It delivers non-blocking throughput with a total switching capacity of 192 Gbps. The device operates at a maximum clock frequency of 125 MHz and supports data rates up to 192 Gb/s. It utilizes an FCBGA-484 package with a lead count of 484 pins. Operating temperatures range from -40°C to +85°C, and it requires supply voltages of 1 V, 2.5 V, and 3.3 V.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream ports
• Includes on-board DMA support with internal buffering and flow control credits

Applications

• High-performance server system interconnects
• Storage area network infrastructure
• Communication equipment requiring deterministic switching
• Embedded systems needing multi-root PCIe topology

Procurement Notes

This component is officially listed as obsolete and discontinued by the manufacturer. Availability is restricted to remaining stock or secondary market sources. Verify end-of-life notifications and check for valid RoHS compliance status before procurement planning. Ensure compatibility with existing design constraints due to the discontinued status.

Selection Notes

Select this part only if legacy support for PCIe Gen2 with 24 lanes and 6 ports is required. Consider the FCBGA-484 package size and thermal requirements during PCB layout. Evaluate alternative modern switches if new designs are initiated, as this specific model is no longer in active production. Confirm voltage domain compatibility for 1V, 2.5V, and 3.3V rails.

Part Context

The 89H24NT6AG2ZCHL8 belongs to the IDT/Renesas 89HPES24NT6G2 series of PCIe switches. It was designed to provide high-bandwidth, low-latency connectivity for complex system architectures. The ZCHL8 suffix indicates specific packaging and environmental characteristics within the broader product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements may not exist. Engineers should evaluate newer generations of PCIe switches from Renesas or other vendors that offer similar lane counts and port configurations.
