89H24NT24G2ZCHLI

Overview

The Renesas 89H24NT24G2ZCHLI is a PCI Express Gen2 system interconnect switch providing 24 lanes and 24 ports. It operates with a maximum clock frequency of 125 MHz and supports data rates up to 192 Gb/s. The device utilizes a 32/64-bit data bus width and functions within a temperature range of -40°C to +85°C. Power supply requirements include voltages of 1 V, 2.5 V, and 3.3 V. It is housed in a 324-FCBGA package (19x19 mm) designed for surface mount installation.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication
• Features on-board DMA support and internal buffering optimized for large payloads

Applications

• High-performance server system interconnect switching
• Storage area network (SAN) fabric expansion
• Multi-root I/O virtualization environments
• Industrial control systems requiring deterministic latency

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance requirements as the specific variant may not meet current environmental standards. Validate package integrity upon receipt to ensure solder joint reliability for the FCBGA configuration. Check for obsolescence notices or alternative sourcing options given the discontinued status indicated in public records.

Selection Notes

Select this component when 24-port PCIe Gen2 connectivity is required for non-blocking throughput. Ensure design compatibility with 1V, 2.5V, and 3.3V power domains. Verify thermal management solutions for the -40°C to +85°C operating range. Consider the 324-FCBGA footprint constraints during PCB layout planning. Evaluate partitioning needs for multi-root support if applicable to the system architecture.

Part Context

This part belongs to the Renesas 89H series of PCIe switches, specifically the Gen2 generation. It shares architectural similarities with other models like the 89H24NT6AG2 but offers higher port density. The ZCHLI suffix indicates specific packaging and material configurations distinct from other variants in the family. It serves as a critical node for expanding PCIe topology in enterprise and industrial infrastructure.

Replacement Considerations

Publicly confirmed substitute part numbers are not available. The component is listed as obsolete or end-of-life in distributor records. Designers should consult Renesas for potential next-generation replacements or evaluate pin-compatible alternatives with similar lane counts and Gen2 specifications.
