BCM56160B0KFSBG

Overview

The Broadcom BCM56160B0KFSBG is a System-on-a-Chip (SoC) Ethernet switch controller designed for enterprise edge applications. It integrates an ARM Cortex-A9 processor, 2.0 MB packet buffer, and sixteen embedded copper Gigabit PHYs within a 29 mm x 29 mm BGA package. The device supports up to twenty-four GbE ports, with eight capable of multirate operation at 2.5 Gbps for Wi-Fi access points. Four high-speed SerDes lanes provide stacking or uplink bandwidth configurable as XFI, HiGig, HGd, or 40GbE. Built on low-power 28 nm CMOS technology, it features IEEE 1588v2 support, IPv4/IPv6 L3 processing, and Energy Efficient Ethernet.

Feature Summary

• High integration with sixteen embedded copper Gigabit PHYs and an ARM A9 processor in a compact footprint
• Multirate port flexibility supporting both standard Gigabit and 2.5 Gbps speeds for modern wireless access points
• Advanced Content-Aware Engine providing three-stage classification, policing, and queuing capabilities
• Robust security features including enhanced Denial of Service (DoS) protection and tunnel visibility

Applications

• Light L3-managed wiring closet switches for enterprise environments
• MTU/MDU switches for service provider networks
• Cost-sensitive edge connectivity platforms requiring high port density
• Industrial Ethernet applications utilizing IEEE 1588 synchronization

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact silicon stepping and package configuration. Ensure compatibility with the required DDR3 memory interface and PCIe connections during system design. Confirm that the selected variant matches the intended application requirements for integrated PHYs versus external PHY configurations.

Selection Notes

Select this component for designs prioritizing high integration and reduced bill-of-materials cost. The inclusion of sixteen copper PHYs eliminates the need for external transceivers on access ports. Evaluate the 40GbE stacking capability if non-blocking 48-port cascaded systems are required. Consider the ARM A9 processor resources for running network operating systems or management agents.

Part Context

This part belongs to the StrataXGS family of switching solutions. It builds upon the BCM56150 architecture, adding support for priority flow control, IEEE 802.1br port extender functionality, and expanded table sizes. The device utilizes the HiGig2 protocol for inter-chip communication, enabling seamless stacking with other compatible StrataXGS devices.

Replacement Considerations

The BCM56162 serves as a pin-compatible alternative lacking the 40GbE stacking capability but retaining the integrated PHYs. For higher performance requirements, consider the BCM56170 series. Verify mechanical and electrical compatibility when substituting components within existing board layouts.
