89H16NT16G2ZAHLGI

Overview

The Renesas 89H16NT16G2ZAHLGI is a PCIe Gen2 system interconnect switch providing 16 lanes and 16 ports. It operates with supply voltages of 1 V, 2.5 V, and 3.3 V. The device supports a maximum clock frequency of 125 MHz and a data rate of 128 Gb/s. It utilizes a 324-FCBGA package with dimensions of 19x19 mm. The component functions within an operating temperature range of 0°C to +70°C and features surface mount installation. It supports 32/64-bit data bus widths.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream configurations

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• PCIe switch interface implementations

Procurement Notes

Verify the specific suffix ZAHLGI against official Renesas documentation to confirm lead-free status and industrial temperature grade requirements. Confirm RoHS compliance details as manufacturing changes may affect regulatory status. Check current lifecycle status as this model is listed as obsolete in public records. Ensure compatibility with existing PCB footprints for the 324-FCBGA package before procurement planning.

Selection Notes

Select this component when a deterministic, non-blocking PCIe Gen2 switch with 16 ports is required. Consider the 324-FCBGA package constraints and thermal management needs for the specified voltage rails. Evaluate partitioning requirements for multi-root support if applicable. Verify that the industrial temperature range meets the target environment specifications.

Part Context

This part belongs to the 89H16N family of PCIe switches manufactured by Renesas Electronics, formerly IDT. The series provides high-bandwidth interconnect solutions for complex systems. The specific suffix indicates packaging and environmental variations within the broader product line. Public documents reference the underlying 89HPES16NT16G2 datasheet for technical specifications.

Replacement Considerations

Public records list the entire 89H16NT16G2 family as obsolete. No direct active substitutes are confirmed in the provided source material. Engineers must evaluate alternative PCIe switch families from other manufacturers or consider redesigning for newer generation interfaces.
