89H32NT24BG2ZCHL8

Overview

The 89H32NT24BG2ZCHL8 is a PCI Express switch interface integrated circuit manufactured by Renesas Electronics. It provides 32 PCIe Gen2 lanes and 24 switch ports, delivering high-performance, deterministic system interconnect switching with non-blocking throughput. The device operates on a 3.3V supply voltage and supports data rates up to 256 Gb/s. It utilizes an FCBGA-484 package measuring 23x23 mm for surface mount installation. The component functions as a specialized interface IC designed for partitionable switch architectures supporting multi-root configurations.

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

Applications

• High-performance system interconnect switching
• PCIe switch interface implementations
• Multi-root server architectures

Procurement Notes

Verify the specific suffix ZCHL8 against official Renesas documentation to confirm lead-free status and carrier type specifications. Confirm current product lifecycle status as obsolete or end-of-life through authorized channels before procurement planning. Ensure compatibility with existing PCB footprints for the 484-FCBGA package.

Selection Notes

Select this component when designing systems requiring 32 lanes and 24 ports of PCIe Gen2 connectivity. Evaluate thermal management requirements for the 484-ball BGA package. Consider alternative models within the 89H series if higher lane counts or different port densities are required for the target application.
