BCM5315x Family

Ultra-Low Power GE switch 10GE uplink ports

Currently Viewing:

Bradcom's BCM5315X is a family of highly integrated Ethernet switches that are optimally designed for low-power SMB, Enterprise, Service-Provider and Industrial applications that rapidly transition to Gigabit-Ethernet connectivity and beyond.

Building on the industry-leading 28 nm RoboSwitch™ architecture the product line includes multiple models with 10 and 11 ports that support 100M/1GE/2.5GE and 10GE speeds.  

The BCM5315X family targets new cost-effective low-power applications with 1GE/2.5GE/10GE connectivity. Among those, Unmanaged and Web-Managed SMB switches, Port-Extender (PE) enterprise switches, enterprise routers and security appliances, next generation Industrial solutions with Time Sensitive Network (TSN) support and Service Provider access equipment. 

The BCM5315X product line takes advantage of an integrated ARM Cortex M7 CPU to offer on-chip support for an embeeded Operating System named Robo-OS(TM). The product line is supported by multitude of software suites for different operational modes, such as, Unmanaged, Web-Managed, Port-Extender and Fully-Managed.
