89HPES24T6ZABX

Overview

The Renesas Electronics Corporation 89HPES24T6ZABX is a PCI Express Gen2 system interconnect switch featuring 24 lanes and 6 ports. It provides non-blocking switching architecture optimized for high-performance applications, supporting multiple simultaneous point-to-point traffic flows. The device integrates SerDes capable of 5.0 GT/s operation and offers up to 192 Gbps of switching capacity. It supports flexible port configurations with automatic link width negotiation and includes features such as cross-linking, channel inversion, and dynamic partitioning for logical isolation within the same device.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnects
• Supports dynamic reconfiguration of switch partitions for multi-root support
• Integrates Non-Transparent Bridging (NTB) functions for external domain communication
• Features low-latency passthrough architecture with internal buffering

Applications

• Server systems requiring high-speed data transfer
• Storage area networks (SAN)
• Communication infrastructure equipment
• Embedded systems with I/O expansion needs

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific package variants against official datasheets before procurement. Ensure supply chain stability as this component may be subject to discontinuation notices or limited stock conditions in certain regions.

Selection Notes

Select this component when designing systems requiring deterministic latency and high bandwidth PCIe Gen2 connectivity. Evaluate thermal management requirements given the FCBGA package type. Consider pin compatibility and signal integrity constraints during PCB layout. Verify that the application benefits from the specific NTB and partitioning capabilities offered by this switch architecture over standard routing solutions.

Part Context

This part belongs to the Renesas IDT 89HPES series of PCIe switches, designed for enterprise and industrial applications. It succeeds earlier generations by offering enhanced throughput and flexibility. The 89HPES24T6ZABX variant specifically targets designs needing robust multi-port interconnectivity with advanced bridging features for complex system topologies.

Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers. Cross-reference pinouts and electrical specifications carefully. Generic PCIe switches may not support the specific NTB or partitioning features required.
