89H16NT16G2ZCHLI

Overview

The Renesas 89H16NT16G2ZCHLI is a specialized interface integrated circuit functioning as a PCI Express Gen2 system interconnect switch. It provides 16 lanes and 16 ports for high-performance, deterministic switching with non-blocking throughput. The device operates on a 3.3V supply voltage and utilizes a 324-FCBGA package measuring 19x19 mm. It supports surface mount installation and includes internal buffering and flow control credits optimized for maximum bandwidth and large payloads.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partionable switch architecture enabling true multi-root support capabilities
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication
• Features movable upstream support and onboard DMA for flexible topology configuration

Applications

• High-performance computing server backplanes
• Storage area network infrastructure switches
• Industrial automation controller interconnects
• Telecommunications base station data routing

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or alternative packaging types. Confirm RoHS compliance status, as variants differ; this specific suffix indicates lead-free composition but verify against current environmental regulations before procurement planning.

Selection Notes

Select this part when designing systems requiring 16-port PCIe Gen2 connectivity with low latency and high determinism. Ensure the design accommodates the 324-FCBGA footprint and 3.3V power requirements. Verify that the application benefits from its non-blocking architecture and supports the necessary thermal dissipation for the FCBGA package in the target environment.

Part Context

The 89H16NT16G2ZCHLI belongs to the IDT 89HPES16N family of PCI Express switches, later acquired by Renesas Electronics. This series was designed to provide scalable interconnect solutions for enterprise and industrial markets. The ZCHLI suffix denotes specific packaging and material attributes within the broader 89H16NT16G2 product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers must evaluate newer generations of PCIe switches from Renesas or other manufacturers, ensuring compatibility with Gen2 speeds and port counts.
