89H32NT8AG2ZAHLI8

Overview

The Renesas 89H32NT8AG2ZAHLI8 is a PCIe Gen2 system interconnect switch providing 32 lanes and 8 ports. It operates with maximum clock frequencies of 125 MHz and supports data rates up to 256 Gb/s. The device utilizes a non-blocking architecture optimized for high-performance system interconnects. Power supply requirements include voltages of 1 V, 2.5 V, and 3.3 V. It functions within an operating temperature range of -40°C to +85°C. The component is housed in a 484-FCBGA package measuring 23x23 mm and is designed for surface mount installation.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput for multiple traffic flows regardless of switch loading
• Partitionable switch architecture enabling true multi-root support for flexible system configurations
• Internal buffering and flow control credits optimized for maximum bandwidth and large payload transactions

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area network (SAN) fabric switches

Procurement Notes

This component is identified as obsolete or end-of-life by the manufacturer. Availability is restricted, and verification of current stock status through authorized distributors is required before procurement planning. Compliance with RoHS directives should be confirmed via specific datasheet documentation due to potential legacy manufacturing variations.

Selection Notes

Select this part when a fixed configuration of 32 lanes and 8 ports is required for PCIe Gen2 systems. Verify that the 484-FCBGA footprint matches the PCB layout constraints. Ensure power delivery networks support the specified 1 V, 2.5 V, and 3.3 V rails simultaneously.

Part Context

This model belongs to the 89H32NT series of PCIe switches from Renesas Electronics. It shares architectural similarities with other models in the family but differs in port count and lane configuration. Related variants include the 89H32NT8AG2ZBHLGI8 and 89H32NT8BG2ZCHLGI8, which offer similar functionalities with potentially different packaging or commercial/industrial temperature grades.

Replacement Considerations

Direct replacements are limited due to the obsolete status. Consider the 89H32NT8AG2ZBHLGI8 as a functional equivalent within the same series. Evaluate newer generations such as the 89HPES series for long-term availability, noting differences in PCIe generation support and pin compatibility.
