89H32NT24AG2ZCHL8

Overview

The 89H32NT24AG2ZCHL8 is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics Corporation. It provides 32 PCIe Gen2 lanes and 24 switch ports within a non-blocking architecture optimized for high-performance system interconnect partitioning. The device supports true multi-root configurations through partitionable switch architecture and multiple Nontransparent Bridging (NTB) functions. Key electrical parameters include operation at 1 V, 2.5 V, and 3.3 V supply voltages, with a maximum clock frequency of 125 MHz. It features a data rate of 192 Gb/s and supports 32/64-bit data bus widths. The component is housed in a 484-FCBGA package measuring 23x23 mm, designed for surface mount installation.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput for multiple traffic flows regardless of switch loading.
• Partitionable switch architecture enabling true multi-root support for flexible system configurations.
• Support for multiple Nontransparent Bridging (NTB) functions to facilitate isolated domain communication.
• On-board DMA support combined with internal buffering and flow control credits optimized for large payloads.

Applications

• High-performance server system interconnect switching
• Storage area network (SAN) infrastructure
• Telecommunications base station backplane connectivity

Procurement Notes

Verify the specific ordering suffix ZCHL8 against official Renesas documentation to confirm lead-free status and carrier type specifications. Confirm current product lifecycle status as obsolete or end-of-life prior to procurement planning. Ensure compatibility with existing PCB footprint designs utilizing the 484-FCBGA package dimensions.

Selection Notes

Select this component when designing systems requiring deterministic switching for 32 PCIe Gen2 lanes across 24 ports. Consider the 484-FCBGA package constraints and thermal requirements for surface mount assembly. Evaluate the need for partitionable architectures and NTB capabilities if multi-root or isolated domain communication is required for the target application.

Part Context

This part belongs to the 89H series of PCIe switches from Renesas, specifically designed for Gen2 speeds. It shares architectural similarities with other models like the 89H24NT24G2 but offers distinct lane and port counts. The ZCHL8 suffix indicates specific packaging and material compliance attributes defined by the manufacturer for this variant.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify availability of alternative Renesas PCIe switch models with comparable lane and port configurations if direct replacement is necessary.
