89H16NT16G2ZAHL8

Overview

The 89H16NT16G2ZAHL8 is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, functioning as a PCI Express switch. It provides 16 PCIe Gen2 lanes and 16 ports for high-performance system interconnect switching. The device operates on a 3.3V supply voltage and utilizes a 324-FCBGA package with dimensions of 19x19 mm. It supports non-blocking throughput and includes features such as 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 system interconnect switching
• Multi-root support configurations requiring partitionable switch architecture
• Applications demanding low latency and deterministic data transfer

Procurement Notes

This component is officially listed as obsolete or end-of-life. Verification of availability requires checking authorized distributors for remaining stock or alternative packaging types. Confirm RoHS compliance status, as specific suffixes may indicate lead-free or restricted substance variations. Ensure the 324-FCBGA package compatibility matches the target PCB design before procurement.

Selection Notes

Select this part when a 16-lane, 16-port PCIe Gen2 switch is required for non-blocking system interconnects. Verify that the 3.3V power supply aligns with the system design. Consider the 324-FCBGA footprint constraints. Since the base model is obsolete, confirm if the ZAHL8 suffix offers specific environmental or packaging attributes distinct from other variants like ZCHLGI8.

Part Context

The 89H16NT16G2ZAHL8 belongs to the 89HPES16NT16G2 family of PCI Express switches. This series is designed for deterministic system interconnect switching with full line-rate throughput. The manufacturer, Renesas Electronics Corporation, acquired the original IDT technology base. The device is part of a broader portfolio of interface ICs focused on high-speed connectivity solutions.

Replacement Considerations

Publicly confirmed substitute part numbers include 89H16NT16G2ZCHLGI8 and 89H16NT16G2ZBHLGI8. These variants share the same core switching functionality but may differ in RoHS compliance, temperature grade, or packaging type. Verify pinout and electrical specifications against the datasheet before substitution.
