89H16NT16G2ZCHLG8

Overview

The 89H16NT16G2ZCHLG8 is a specialized PCI Express switch interface integrated circuit manufactured by Renesas Electronics Corporation. 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 features 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 RoHS compliance status, as specific suffixes indicate varying environmental certifications. Replacement planning should account for the discontinued status to ensure long-term supply chain stability.

Selection Notes

Select this part when a 16-lane, 16-port PCIe Gen2 switch is required for non-blocking data paths. Ensure the design accommodates the 324-FCBGA footprint and 3.3V power domain. Verify that the industrial temperature grade meets operational requirements if applicable. Consider the obsolete status during initial selection to mitigate future sourcing risks.

Part Context

This device belongs to the 89HPES16NT16G2 family of PCI Express switches. It serves as a system interconnect solution bridging multiple PCIe endpoints. The ZCHLG8 suffix denotes specific packaging and environmental attributes within the broader product line, distinguishing it from other variants like ZAHL or ZBHL series components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers must evaluate pin-compatible alternatives or redesign the PCB layout for newer generation PCIe switches offered by Renesas or other vendors.
