89H16NT16G2ZCHLGI8

Overview

The 89H16NT16G2ZCHLGI8 is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, designed for high-performance system interconnect switching. It functions as a PCI Express Gen2 switch providing 16 lanes and 16 ports with non-blocking architecture. The device operates at a maximum clock frequency of 125 MHz and supports data rates up to 128 Gb/s. It utilizes a 324-FCBGA package measuring 19x19 mm and requires supply voltages of 1 V, 2.5 V, and 3.3 V. The component is rated for an industrial temperature range from -40°C to +85°C and has a Moisture Sensitivity Level (MSL) of 4.

Feature Summary

• Non-blocking switch architecture optimized for deterministic system interconnect switching across multiple traffic flows.
• Supports partitionable switch architecture enabling true multi-root support and multiple Nontransparent Bridging (NTB) functions.
• Includes onboard DMA capabilities and internal buffering with flow control credits to maximize bandwidth and handle large payloads.

Applications

• High-performance computing system interconnects
• Industrial automation networking
• Telecommunications infrastructure switching

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or alternative packaging types. Buyers must confirm RoHS compliance status, as specific suffixes indicate varying environmental certifications. Lead times and minimum order quantities are subject to distributor inventory levels rather than manufacturer production schedules.

Selection Notes

Select this part when a PCIe Gen2 switch with 16 ports and 16 lanes is required for non-blocking throughput. Ensure the design accommodates the 324-FCBGA footprint and the specific voltage rails of 1V, 2.5V, and 3.3V. Verify that the industrial temperature grade (-40°C to +85°C) meets the operational environment requirements. Confirm that the MSL 4 rating aligns with the assembly process capabilities.

Part Context

The 89H16NT16G2ZCHLGI8 belongs to the 89HPES16NT16G2 family of PCIe switches. It shares core functional specifications with variants such as 89H16NT16G2ZCHLG and 89H16NT16G2ZAHLI, differing primarily in packaging type (Reel vs. Tray) and RoHS compliance status. The 'I' suffix typically denotes the industrial temperature grade, while 'G' indicates lead-free composition.

Replacement Considerations

As the part is obsolete, direct substitutes may be limited. Review the manufacturer's product change notices for recommended alternatives within the same family. Consider evaluating newer PCIe generation switches if backward compatibility constraints allow, ensuring pinout and electrical parameter alignment.
