BCM53112 Product Brief 15-Port Integrated Fast Ethernet Switch with High-Speed 1GbE/2.5GbE SGMII Uplink Interfaces Description The Broadcom BCM53112 is a highly integrated, Fast Ethernet (FE) switch designed for high-end FE applications such as next-generation Industrial Ethernet and Time Sensitive Networks (TSNs). With eight 10/100BASE-T ports (with integrated EPHYs), four 100FX/1000FX SGMII ports, and an additional two 1GbE/2.5GbE SGMII+ ports, the switch is optimally designed for 100 Mb/s and Hybrid-speed SMB and Industrial applications that take advantage of high-speed uplinks connectivity, both copper and fiber. The BCM53112 is based on the industry-leading 28 nm RoboSwitch architecture, also known as Robo-2. The switch integrates a powerful ARM Key Features Cortex-M7 CPU that enables a customer to design complete SMB and Eight 10/100BASE-T ports with Industrial platforms without relying on external processors. The switch is integrated EPHYs. also equipped with high-end blocks that are required in many advanced applications. It includes an advanced QoS mechanism, a flexible compact Four 100FX/1000FX (SGMII) ports. filter processor (CFP), sophisticated VLAN manipulation capability, security Two 100FX/1000FX/2500FX features, packet synchronization for time-sensitive networks, and more. (SGMII+) ports. An integrated ARM Cortex-M7 CPU. The BCM53112 can be used with various software solutions designed for a multitude of applications. It can be used with basic, unmanaged software An RGMII, MII, and RvMII port to to design unmanaged switches that require no advanced functionality connect to an external CPU. or VLAN segregation. It can be used with web-managed software to Cascading that enables the creation construct a high-end web-controlled switch and with a fully featured of unified, single-CPU managed, 15- SDK software suite to design managed devices that are controlled by an to 28-port switch. external CPU.

Home gateway Support for virtual switching instances (VSI) for explicit segregation of bridging domains with advanced VLAN translation and encapsulation (for example, MAC-in-MAC). RoboSwitch TechnologyProduct Brief Benefits (cont) Port-extender support, per IEEE 802.1BR, for designing modular chassis devices or pizza box platforms with remote port extensions. Advanced TSN protocol support, such as IEEE 802.1Qav, 802.1Qbv, 802.1ASrev, and 802.1Qci, for scheduling time- critical traffic streams across an entire network domain. Delivered with unmanaged software, web-managed software, or two different managed SDK software packages (RoboSwitch SDK and Network Switch SDK).
