89H16NT16G2ZCHLGI

Overview

The 89H16NT16G2ZCHLGI is a specialized 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 3.3V supply voltage and utilizes a 324-FCBGA package measuring 19x19 mm. It supports industrial temperature ranges from -40°C to +85°C and features RoHS3 compliance. Key technical specifications include a maximum clock frequency of 125 MHz, data rates up to 128 Gb/s, and support for 32/64-bit data bus widths.

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
• Includes onboard DMA support and internal buffering with flow control credits

Applications

• High-performance computing system interconnects
• Industrial automation networking infrastructure
• Telecommunications equipment requiring deterministic latency

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 RoHS3 status and lead-free composition through current datasheets before integration into new designs.

Selection Notes

Select this part for applications requiring 16-port PCIe Gen2 connectivity with low latency. Ensure compatibility with 3.3V logic levels and FCBGA324 footprint constraints. Verify that the industrial temperature grade meets environmental requirements. Consider end-of-life implications for long-term production planning.

Part Context

This device belongs to the 89HPES16N series of PCI Express switches manufactured by Renesas Electronics. It succeeds earlier IDT-branded variants in the same functional family. The ZCHLGI suffix indicates specific packaging, temperature grade, and regulatory compliance attributes within the broader 89H16NT16G2 product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Renesas official resources for current portfolio replacements or evaluate pin-compatible alternatives from other vendors if necessary.
