89H16NT16G2ZCHL8

Overview

The Renesas Electronics Corporation 89H16NT16G2ZCHL8 is a specialized interface integrated circuit functioning as a PCI Express switch. It provides 16 PCIe Gen2 lanes and 16 ports for high-performance, deterministic system interconnect switching. The device supports non-blocking architecture with full line rate throughput across all ports regardless of switch loading. It operates on a 3.3V supply voltage and utilizes a 324-FCBGA package measuring 19x19 mm. The component is designed for surface mount installation and includes internal buffering and flow control credits optimized for maximum bandwidth.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream support
• Includes onboard DMA capabilities with internal buffering and flow control credits

Applications

• High-performance computing system interconnects
• Storage area network infrastructure
• Telecommunications equipment requiring deterministic switching

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or end-of-life inventory. Buyers must confirm the specific suffix ZCHL8 matches their design requirements, as packaging and lead-free status vary across the product family. Due to the discontinued status, long-term supply assurance is not guaranteed through standard channels.

Selection Notes

Engineers selecting this part should verify compatibility with PCIe Gen2 specifications and ensure the 324-FCBGA footprint fits the PCB layout. The absence of RoHS compliance in some variants within this series necessitates checking the specific ordering code against environmental regulations. Alternative solutions from newer generations may offer improved power efficiency and support for higher PCIe speeds.

Part Context

The 89H16NT16G2ZCHL8 belongs to the IDT 89HPES16N family of PCI Express switches, which was later acquired by Renesas Electronics. This series was designed to provide scalable switching solutions for enterprise and industrial markets. The specific ZCHL8 suffix indicates a tray-packaged version with specific material composition compared to reel-based or lead-free variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Renesas or IDT technical support for current replacement recommendations or next-generation equivalents that maintain pin-to-pin compatibility.
