BCM56372A2KFSBG

Overview

The BCM56372A2KFSBG is a premium Ethernet switch integrated circuit manufactured by Broadcom Limited. It belongs to the Tomahawk series, designed for high-performance data center switching applications. The device supports 28 ports of 25 Gigabit Ethernet (25GbE). It features a scalable architecture with a switch fabric capacity of 700 Gbps per side, providing non-blocking performance for enterprise and cloud infrastructure. The component utilizes a lead-free FCBGA package suitable for industrial temperature ranges.

Feature Summary

• Supports 28-port 25GbE connectivity for high-density access layers
• Features a 700 Gbps bidirectional switch fabric for non-blocking throughput
• Includes hardware-accelerated network virtualization capabilities
• Integrates advanced security features including MACsec encryption

Applications

• Data center spine and leaf switch architectures
• Enterprise core and aggregation layer networking
• High-performance computing cluster interconnects

Procurement Notes

Verify the specific ordering suffix against the official Broadcom datasheet to ensure correct package type and temperature rating. Confirm RoHS compliance status through manufacturer documentation. Request the latest revision level to guarantee compatibility with current design requirements. Validate authenticity via authorized distribution channels only.

Selection Notes

Select this component when 25GbE port density is required without the bandwidth overhead of higher-tier Tomahawk models. Evaluate power consumption constraints relative to the 700 Gbps fabric limit. Ensure PCB layout supports the specific FCBGA pinout and thermal dissipation needs defined in the mechanical drawings.

Part Context

This part is part of Broadcom's Tomahawk family, bridging the gap between lower-speed Gigabit solutions and higher-capacity Terabit switches. It addresses the growing demand for 25GbE servers while maintaining cost efficiency. The A2KFSBG suffix denotes specific packaging and commercial/industrial grade variations within the broader product line.

Replacement Considerations

Direct replacements are limited due to proprietary architecture. Consider BCM56371 or BCM56373 variants if port count or fabric bandwidth requirements differ. Verify pin-to-pin compatibility before substituting any alternative components.
