BCM56150A0KFSBLG

Overview

The BCM56150A0KFSBLG is a highly integrated System-on-Chip (SoC) designed for 24-port managed Gigabit Ethernet switches with four 10GbE uplinks. It features sixteen integrated copper PHYs, an ARM A9 processor, and six QSGMII interfaces. The device supports up to four XFI or two XFI and two HiGig ports for stacking and uplinking. It includes a 2MB packet buffer expandable to 4MB in 48-port configurations, intelligent memory management, and support for IPv4/IPv6, Low Power Ethernet, and IEEE 1588v2 time synchronization.

Feature Summary

• High integration of switching fabric, CPU, and physical layers on a single chip
• Support for Layer 3 management features and advanced security engines
• Flexible port configuration for stacking and high-speed uplinks
• Integrated power management and thermal monitoring capabilities

Applications

• Lightweight Layer 3 managed distribution cabinet switches for enterprise networks
• Multi-Tenant Unit (MTU) and Multi-Dwelling Unit (MDU) switches for service providers
• Edge connectivity solutions requiring cost-effective high-density ports

Procurement Notes

Verify the specific suffix KFSBLG against official Broadcom documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing PCB footprints and thermal design requirements. Confirm supply chain authenticity through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for designs requiring a balance of high port density and Layer 3 capabilities within a compact form factor. Consider the integrated ARM A9 processor for custom application logic. Evaluate the need for external PHYs if more than sixteen copper ports are required, as the internal count is fixed at sixteen.

Part Context

This part belongs to the Broadcom BCM56150 series, which targets the edge access and distribution market. It serves as a core solution for service providers and enterprises needing scalable, manageable switch architectures. The series emphasizes high integration to reduce bill-of-materials costs and board space.

Replacement Considerations

Check for updated revisions within the BCM56150 family that may offer improved performance or different packaging options. Verify pin-to-pin compatibility before substituting with other Broadcom SoCs like the BCM56162, noting differences in uplink speeds and buffer sizes.
