General Descriptions

Broadcom's BCM53154/BCM53156/BCM53158 is a family

of highly integrated Ethernet switches that are optimally

designed for cost-effective low-power applications in the

SMB, Enterprise, Service-Provider, SOHO, and Industrial-

Ethernet markets that rapidly transition to Gigabit-Ethernet

connectivity and beyond. The BCM53154/BCM53156/

BCM53158 is based on the industry-leading 28 nm

RoboSwitch? architecture, also known as Robo 2. The

product line includes multiple models with 6 to 15 interfaces

that support 100M/1GE/2.5GE and 10GE of bandwidth. The

various models support Unmanaged, Web-Managed, and

Managed modes of operation. The BCM53154/BCM53156/

BCM53158 is designed for standalone low port-count

configurations, high port-count configurations with support

for cascading, and a Port-Extender configuration with

support for IEEE 802.1BR.

The BCM53154/BCM53156/BCM53158 allows customers

to design complete product platforms that target new costeffective

low-power applications demanding 1GE/10GE

connectivity. Among those, SMB switch with 10G uplinks,

Enterprise switches, routers and security appliances, next

generation Industrial Ethernet switches, and Service

Provider access equipment.

The BCM53154/BCM53156/BCM53158 is also designed to

support high-end applications that require advanced QoS,

flexible classification of traffic, sophisticated VLAN

manipulation, security features, packet synchronization for

time-sensitive networks, and more. The product line takes

advantage of a low-power integrated ARM Cortex-M7 CPU

to offer on-chip support for certain protocols, including

xSTP, LLDP, and IGMP as well as tools for monitoring and

troubleshooting. The product line is offered in Commercialgrade

as well as Industrial-grade temperature ranges.
