89H32NT8AG2ZCHL

Overview

The Renesas 89H32NT8AG2ZCHL is a PCIe Gen2 system interconnect switch providing 32 lanes and 8 ports. It operates with a maximum clock frequency of 125 MHz and supports data rates up to 256 Gb/s. The device requires supply voltages of 1 V, 2.5 V, and 3.3 V. It functions within an operating temperature range of -40°C to +85°C. The component is housed in a 484-FCBGA package (23x23 mm) designed for surface mount installation.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Supports true multi-root configurations through partitionable switch architecture
• Includes onboard DMA support and internal buffering with flow control credits

Applications

• High-performance server system interconnect switching
• Storage area network infrastructure
• Telecommunications base station backplane connectivity

Procurement Notes

This component is identified as obsolete or end-of-life by the manufacturer. Availability is restricted, and distributors may not stock this specific part number. Verification of current lifecycle status and alternative sourcing channels is required before integration into new designs.

Selection Notes

Designers should evaluate the 89H32T8G2 series variants for equivalent pinouts and electrical characteristics. Consideration must be given to the transition from tray to reel packaging options available in related suffixes. Thermal management requirements for the FCBGA package must align with the specified industrial temperature grade limits.

Part Context

This part belongs to the IDT/Renesas 89H32NT8AG2 family of PCIe Gen2 switches. It shares architectural similarities with other models like the 89H32NT24AG2 but differs in port count. The family targets deterministic latency applications requiring non-blocking bandwidth across multiple PCIe domains.

Replacement Considerations

Direct substitutes include the 89H32NT8AG2ZBHLGI8 variant, which offers identical core functionality with different packaging and lead-free specifications. Other family members such as the 89H32T8G2ZCBLI provide comparable lane counts but require verification of pin compatibility.
