89H32NT24AG2ZAHL8

Overview

The 89H32NT24AG2ZAHL8 is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 lanes and 24 ports of high-performance, deterministic switching with non-blocking architecture. The device supports full line rate throughput for multiple traffic flows regardless of switch loading. It features a partitionable architecture for multi-root support and includes internal buffering and flow control credits optimized for maximum bandwidth and large payloads.

Feature Summary

• Non-blocking switch architecture optimized for high performance system interconnect
• Partitionable switch architecture enabling true multi-root support
• Supports multiple Nontransparent Bridging (NTB) functions
• On-board DMA support with internal buffering and flow control

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Data center infrastructure requiring low latency and low power consumption

Procurement Notes

Verify the specific suffix ZAHL8 against official Renesas documentation to confirm lead-free status and temperature grade. Confirm package dimensions and moisture sensitivity level prior to PCB design. Check for product change notices or end-of-life announcements as this component series may have legacy status.

Selection Notes

Select this component when 32 lanes and 24 ports are required for PCIe Gen2 systems. Ensure the design supports the FCBGA 484 package. Verify power supply requirements for 1V, 2.5V, and 3.3V rails. Consider thermal management solutions suitable for surface mount installation in high-density environments.

Part Context

This part belongs to the 89H32NT24G2 family of PCIe switches. It shares architectural similarities with other models in the series but differs in pinout, packaging, and specific electrical characteristics defined by the ZAHL8 suffix. It is designed for deterministic switching applications requiring high throughput.

Replacement Considerations

Direct substitutes include other variants within the 89H32NT24AG2 family such as 89H32NT24AG2ZCHLGI or 89H32NT24AG2ZBHLGI, provided pin compatibility and electrical specifications match the original design requirements.
