89H24NT6AG2ZAHLI

Overview

The Renesas 89H24NT6AG2ZAHLI is a PCIe Gen2 system interconnect switch providing 24 lanes and 6 ports. It operates with a maximum clock frequency of 125 MHz and supports data rates up to 192 Gb/s. The device functions within a voltage range of 1 V, 2.5 V, and 3.3 V. It is designed for industrial temperature environments, operating between -40°C and +85°C. The component utilizes an SMD/SMT installation style in a 484-FCBGA package (23x23 mm). It supports 32/64-bit data bus widths and includes internal buffering for flow control.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support across independent domains
• Supports multiple Nontransparent Bridging (NTB) functions for isolated communication segments

Applications

• High-performance server system interconnects requiring deterministic switching
• Storage area networks needing low-latency data transfer paths
• Communication infrastructure equipment utilizing multi-root configurations

Procurement Notes

Verify the specific suffix ZAHLI against official Renesas documentation to confirm lead-free status and industrial temperature grade specifications. Confirm current availability as distribution channels may list this part as limited supply or obsolete depending on regional inventory. Ensure compatibility with existing PCB footprints for the 484-FCBGA package before procurement.

Selection Notes

Select this component when designing systems requiring 24 PCIe Gen2 lanes with partitionable switching capabilities. Compare against the 89HPES24T6G2ZCALG if commercial temperature grades suffice, noting the latter lacks industrial rating. Verify that the required port configuration matches the six available downstream ports and check power supply requirements for the 1V, 2.5V, and 3.3V rails.

Part Context

This part belongs to the IDT/Renesas 89H series of PCIe switches, specifically the 89H24NT6AG2 family. It serves as a successor or variant to earlier commercial-grade versions like the 89H24NT6AG2ZCHLGI. The series is engineered for scalable I/O expansion and complex system topologies requiring non-transparent bridging and dynamic partitioning.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineering changes should be validated against the official EOL notification documents from Renesas Electronics.
