89H16NT16G2ZAHLGI8

Overview

The Renesas Electronics Corporation 89H16NT16G2ZAHLGI8 is a specialized interface integrated circuit designed for PCI Express switch applications. It provides sixteen PCIe Gen2 lanes and sixteen ports of high-performance, deterministic system interconnect switching. The device operates with a supply voltage of 3.3V and utilizes a 324-FCBGA package measuring 19x19 mm. It supports surface mount installation and features internal buffering optimized for maximum bandwidth. The component has a Moisture Sensitivity Level (MSL) rating of 4, allowing for 72 hours of exposure at room temperature conditions.

Feature Summary

• Non-blocking switch architecture providing full line rate throughput regardless of switch loading
• Partitionable switch architecture enabling true multi-root support capabilities
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream configurations
• Includes on-board DMA support with internal flow control credits optimized for large payloads

Applications

• High-performance system interconnect switching
• PCIe Gen2 network infrastructure
• Multi-root server architectures

Procurement Notes

This component is officially classified as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or alternative packaging types. Confirm RoHS compliance status, as specific suffixes indicate varying environmental certifications. Ensure compatibility with existing PCB footprints before procurement due to potential design changes associated with end-of-life products.

Selection Notes

Select this part when designing systems requiring sixteen independent PCIe Gen2 ports with non-blocking switching capabilities. Verify that the 324-FCBGA package dimensions fit the target board layout. Consider the MSL 4 rating during assembly planning to prevent moisture damage. Evaluate if the partitionable architecture meets the specific multi-root requirements of the application design.

Part Context

The 89H16NT16G2ZAHLGI8 belongs to the 89HPES16NT16G2 family of PCI Express switches manufactured by Renesas Electronics Corporation, formerly IDT. This series is engineered for deterministic data transfer in complex computing environments. The specific suffix indicates tray packaging and lead-free composition within the broader product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the product is obsolete, engineers must evaluate pin-compatible alternatives or redesign the system using newer generation PCIe switches from the manufacturer's current portfolio.
