89H32NT8BG2ZAHLG8

Overview

The Renesas 89H32NT8BG2ZAHLG8 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 accommodates power supply voltages of 1 V, 2.5 V, and 3.3 V. It functions within an operating temperature range from -40°C to +85°C. The component utilizes a 484-FCBGA package measuring 23x23 mm and supports surface mount installation.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication
• Features movable upstream support and onboard DMA for flexible topology configuration

Applications

• High-performance server system interconnect switching
• Storage area network (SAN) fabric construction
• Multi-root I/O virtualization environments
• Enterprise networking infrastructure components

Procurement Notes

Verify the specific suffix ZAHLG8 against official Renesas documentation to confirm lead-free status and packaging type. Confirm current lifecycle status as obsolete or end-of-life through authorized distributors. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.

Selection Notes

Select this model when 32 lanes and 8 ports are required for non-blocking PCIe Gen2 connectivity. Compare against other variants in the 89H32NT series based on port count and voltage requirements. Verify that the 484-FCBGA package dimensions fit the target design constraints and that the industrial temperature range meets environmental specifications.

Part Context

This component belongs to the Renesas 89HPES family of PCIe switches. It shares architectural similarities with models like the 89H32NT24AG2 but offers fewer ports. The part integrates internal buffering and flow control credits to optimize bandwidth utilization for large payloads and low-latency traffic flows.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult Renesas technical support for direct replacements or verify if other members of the 89H32NT series meet the specific lane and port requirements.
