BCM56150A0KFSBG

Overview

The BCM56150A0KFSBG is a highly integrated 24-port managed Gigabit Ethernet switch system-on-chip designed for cost-sensitive edge connectivity applications. It features an ARM A9 processor and integrates sixteen copper-based Gigabit PHYs, eliminating the need for external transceivers on access ports. The device provides four XFI or two XFI combined with two HiGig uplinks/stacking ports, supporting high-density configurations such as 24x GbE switches with 4x 10GbE uplinks. This architecture enables compact form factors suitable for enterprise distribution cabinets and service provider multi-tenant units.

Feature Summary

• Highly integrated system-on-chip combining switching fabric, CPU, and physical layer transceivers
• Built-in sixteen copper Gigabit PHYs for simplified board design and reduced component count
• Integrated ARM A9 processor for advanced management and control plane operations
• Flexible uplink and stacking interface options supporting multiple high-speed protocols

Applications

• Lightweight Layer 3 managed wiring closet switches for enterprise networks
• Multi-tenant unit (MTU) and multi-dwelling unit (MDU) switches for service providers
• Cost-effective edge connectivity solutions requiring high port density

Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range specifications. Ensure compatibility with existing PCB footprints and power delivery requirements. Confirm that the integrated PHY configuration meets the target application's copper cabling standards. Validate firmware support for required Layer 3 features before finalizing procurement decisions.

Selection Notes

Select this component when minimizing bill-of-materials complexity is critical. The integrated PHYs reduce layout constraints compared to discrete PHY solutions. Consider the ARM A9 processing power for applications requiring local routing or management functions. Evaluate the available uplink bandwidth against aggregate traffic demands for the intended deployment scenario.

Part Context

This part belongs to the Broadcom StrataXGS family of Ethernet switching solutions. It targets the access and aggregation layers of modern network infrastructures. The integration level distinguishes it from earlier generations that required separate PHY components. It serves as a foundational building block for compact, high-performance switching hardware.

Replacement Considerations

The BCM56162B0KFSBG offers similar integration but may differ in specific port configurations or performance metrics. Verify pin-to-pin compatibility and software feature parity if considering alternative members of the same product family.
