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
Cortex-M7 CPU that enables a customer to design complete SMB and
Industrial platforms without relying on external processors. The switch is
also equipped with high-end blocks that are required in many advanced
applications. It includes an advanced QoS mechanism, a flexible compact
filter processor (CFP), sophisticated VLAN manipulation capability, security
features, packet synchronization for time-sensitive networks, and more.
Key Features
• Eight 10/100BASE-T ports with
integrated EPHYs.
• Four 100FX/1000FX (SGMII) ports.
• Two 100FX/1000FX/2500FX
(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
to design unmanaged switches that require no advanced functionality
or VLAN segregation. It can be used with web-managed software to
construct a high-end web-controlled switch and with a fully featured
SDK software suite to design managed devices that are controlled by an
external CPU.
• An RGMII, MII, and RvMII port to
connect to an external CPU.
• Cascading that enables the creation
of unified, single-CPU managed, 15-
to 28-port switch.
• Support for advanced QoS, CFP,
VLAN manipulation, up to L4
classification via CFP, and TSN.
The BCM53112 can be used to design standalone platforms with a low port-
count configuration (up to 15 ports) or as part of a cascaded solution that
uses two back-to-back switches with up to 26 front-facing ports, managed
as a single switch entity. The switch is offered in commercial-grade ambient
temperature.
• Support for the IEEE 802.1BR port
extender.
• Power-saving green technology
per IEEE 802.3az Energy Efficient
Ethernet.
Benefits
• Support for cascading mode that enables the creation of a unified, 16- to
26-port switch, unmanaged or managed by a single CPU.
• Support for industrial (−40°C to
+85°C) ambient temperature.
• Support for QoS with hierarchical scheduling, eight egress buffer queues
per-port each with its own shaper, WRED and Tail-drop congestion
avoidance, and dual leaky bucket ingress rate limiters (such as policers).
Applications
• Industrial Ethernet
• Unmanaged/web-managed/
managed SMB switches
• Advanced CFP (such as an access-list engine) that can classify up to L4
headers, supporting up to 1K rules.
• 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™ Technology
Product Brief
Benefits (con’t)
• 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).
