89H24NT6AG2ZCHLI8

Overview

The Renesas 89H24NT6AG2ZCHLI8 is a PCIe Gen2 system interconnect switch providing 24 lanes and 6 ports. It features a non-blocking architecture with full line-rate throughput for multiple traffic flows. The device supports partitionable switching for multi-root configurations and includes Nontransparent Bridging (NTB) functions. It operates within a temperature range of -40°C to +85°C, utilizes a 324-FCBGA package measuring 19x19 mm, and requires 1V, 2.5V, and 3.3V power supplies. The maximum clock frequency is 125 MHz, supporting data rates up to 192 Gb/s.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support through dynamic reconfiguration
• Support for multiple Nontransparent Bridging (NTB) functions with movable upstream capabilities
• Integrated on-board DMA and internal buffering with flow control credits for large payloads

Applications

• High-performance server system interconnects requiring deterministic switching
• Storage area networks needing low-latency data transfer between hosts and peripherals
• Communication infrastructure equipment utilizing peer-to-peer data transfers
• Embedded systems requiring flexible I/O expansion and multi-root topology support

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the specific variant may not meet current environmental standards. Validate package integrity upon receipt, ensuring the FCBGA solder balls are undamaged. Check moisture sensitivity level handling procedures if storage conditions were not strictly controlled prior to installation.

Selection Notes

Select this component when designing systems requiring 24 PCIe Gen2 lanes with six independent ports. Ensure the design accommodates the 324-FCBGA footprint and thermal dissipation needs. Verify that the application benefits from partitionable switching and NTB features rather than standard bridging. Confirm compatibility with existing root complex software drivers for multi-root support implementation.

Part Context

This part belongs to the IDT 89HPES series of PCIe switches, acquired by Renesas Electronics. It serves as a specialized interface IC for expanding PCIe connectivity in complex architectures. The ZCHLI8 suffix indicates specific packaging and lead-free characteristics within the broader 89H24NT6AG2 family, distinguishing it from other pin-compatible or functionally similar variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The component is listed as obsolete. Engineers should evaluate newer generations of PCIe switches from Renesas or other manufacturers that offer compatible lane counts and port configurations while meeting current RoHS directives.
