89H32NT8BG2ZCHLGI

Overview

The Renesas 89H32NT8BG2ZCHLGI 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 data bus widths of 32 or 64 bits and functions within an operating temperature range of -40°C to +85°C. Power supply requirements include voltages of 1 V, 2.5 V, and 3.3 V. It is housed in a 484-FCBGA package measuring 23x23 mm and utilizes surface mount technology for installation.

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 server system interconnect switching
• Storage area network infrastructure
• Enterprise computing platforms requiring multi-root support

Procurement Notes

This component is identified as obsolete or end-of-life by the manufacturer. Availability is restricted, and current stock levels are limited or unavailable through standard distribution channels. Verification of lifecycle status and alternative sourcing strategies is required before procurement consideration.

Selection Notes

Engineers should evaluate partitionable switch capabilities and nontransparent bridging features when designing systems requiring multi-root support. The 484-FCBGA package dimensions and thermal characteristics must align with the target PCB layout constraints.

Part Context

This part belongs to the 89H32NT8AG2 series of PCIe switches from Renesas Electronics. It shares architectural similarities with other models in the family, such as the 89H32NT24AG2, but differs in port count and specific interface configurations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require redesigning the system interface or utilizing compatible components from the same product family with verified pin-to-pin compatibility.
