89H32NT24AG2ZCHLG

Overview

The Renesas 89H32NT24AG2ZCHLG is a PCIe Gen2 system interconnect switch providing 32 lanes and 24 ports. It operates with a maximum clock frequency of 125 MHz and supports data rates up to 256 Gb/s. The device utilizes a 484-FCBGA package and functions within an industrial temperature range of -40°C to +85°C. Power requirements include supply voltages of 1 V, 2.5 V, and 3.3 V. It features a non-blocking architecture optimized for high-performance deterministic switching.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput for multiple traffic flows regardless of load
• Partitionable design supporting true multi-root capabilities and multiple Nontransparent Bridging (NTB) functions
• Integrated on-board DMA support with internal buffering and flow control credits for large payloads

Applications

• High-performance server system interconnects
• Storage area network (SAN) infrastructure
• Industrial automation networking equipment

Procurement Notes

Verify component authenticity through authorized channels due to potential obsolescence. Confirm RoHS compliance status as indicated in official documentation. Check for moisture sensitivity handling requirements prior to assembly. Validate package integrity upon receipt to ensure solder joint reliability during surface mount processes.

Selection Notes

Select this model when requiring 24-port scalability with 32-lane bandwidth capacity. Ensure the PCB layout accommodates the 484-FCBGA footprint. Verify thermal management solutions meet the -40°C to +85°C operational envelope. Confirm power delivery networks support the specified 1 V, 2.5 V, and 3.3 V rails simultaneously.

Part Context

This component belongs to the 89H32NT24BG2 series of PCIe switches manufactured by Renesas Electronics.
