89H32NT24BG2ZBHLG8

Overview

The 89H32NT24BG2ZBHLG8 is a PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 PCIe lanes and 24 switch ports within a non-blocking architecture designed for high-performance deterministic switching. The device supports multiple traffic flows with full line-rate throughput regardless of switch loading. It operates at a maximum clock frequency of 125 MHz and supports data rates up to 256 Gb/s. Power requirements include 1 V, 2.5 V, and 3.3 V supplies. The component is housed in a 484-FCBGA package (23x23 mm) and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream capabilities

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Data center infrastructure

Procurement Notes

Verify the specific suffix ZBHLG8 against official Renesas documentation to confirm exact packaging and material compliance details. Confirm current lifecycle status as obsolete or end-of-life through authorized channels before procurement planning. Ensure compatibility with existing board designs regarding the 484-FCBGA footprint and thermal requirements.

Selection Notes

Select this component when a high-port-count PCIe Gen2 switch is required for non-blocking data transfer. Compare port density against other models like the 89H32NT8BG2 if fewer ports suffice. Verify that the 484-FCBGA package size fits the target PCB layout constraints. Ensure the design supports the necessary 1V, 2.5V, and 3.3V power domains.

Part Context

This part belongs to the 89H32NT24BG2 series of PCIe switches from Renesas. It shares architectural similarities with variants such as the 89H32NT24AG2 but differs in specific suffix designations related to packaging and environmental compliance. It serves as a core interconnect solution for expanding PCIe connectivity in complex systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. As the component is listed as obsolete, consult Renesas for potential last-time buy options or equivalent newer generation switches.
