89H32NT24BG2ZAHLI8

Overview

The 89H32NT24BG2ZAHLI8 is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, designed for high-performance system interconnect switching. It provides 32 PCI Express Gen2 lanes and supports 24 switch ports within a non-blocking architecture. The device operates on a 3.3V supply voltage and utilizes a 484-FCBGA package with dimensions of 23x23 mm. It is classified as a discontinued product.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Internal buffering and flow control credits optimized for maximum bandwidth and large payloads

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Deterministic data throughput environments

Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturing channels. Confirm RoHS compliance status and moisture sensitivity level prior to integration into new designs.

Selection Notes

Engineers requiring equivalent functionality must evaluate alternative PCIe switches from current Renesas portfolios or other vendors. Considerations should include lane count, port density, and package compatibility. Legacy design retention may necessitate specific obsolescence management strategies.

Part Context

This part belongs to the 89H32NT24BG2 series of PCI Express switches. It shares architectural similarities with other models in the family, such as the 89H32NT24BG2ZCHLGI, differing primarily in suffix designators related to packaging or regional specifications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official Renesas lifecycle notices for recommended transition devices.
