89H32NT24AG2ZBHL8

Overview

The Renesas 89H32NT24AG2ZBHL8 is a specialized PCI Express switch interface integrated circuit designed for high-performance system interconnect applications. It provides 32 PCIe Gen2 lanes and 24 switch ports, delivering non-blocking throughput with full line rate capabilities regardless of switch loading. The device operates on a 3.3V supply voltage and utilizes a 484-FCBGA package measuring 23x23 mm. It supports surface mount installation and features internal buffering and flow control credits optimized for maximum bandwidth and large payloads.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Supports true multi-root functionality through partitionable switch architecture
• Enables multiple Nontransparent Bridging (NTB) functions for isolated domain communication

Applications

• High-performance computing system interconnect switching
• Multi-root server architectures requiring deterministic latency
• Storage area network infrastructure components

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance requirements as the base model may not meet current environmental standards. Validate package integrity upon receipt, ensuring the FCBGA solder balls are undamaged. Check moisture sensitivity level handling procedures if storage conditions were not strictly controlled prior to assembly.

Selection Notes

Select this component when designing systems requiring 32 lanes and 24 ports of PCIe Gen2 connectivity. Ensure the PCB layout supports the 484-FCBGA footprint and thermal dissipation needs. Consider power delivery stability for the 3.3V rail. Evaluate alternative models if lead-free compliance or active manufacturing support is mandatory for the production lifecycle.

Part Context

This part belongs to the 89H32NT24 series of PCIe switches from Renesas. It shares architectural similarities with variants like the 89H32NT24BG2ZCHL8 but differs in specific electrical characteristics and packaging suffixes. The 'G2' designation indicates PCIe Generation 2 support, distinguishing it from newer Gen3 or Gen4 retimer and switch products in the broader portfolio.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. The base model 89H32NT24AG2 is listed as obsolete. Engineers should consult Renesas technical support for qualified alternatives or evaluate the 89H32NT24BG2ZCHL8 for potential pin-compatible upgrades if specifications align.
