Data Sheet BCM53156XU Ultra-Low Power Layer2 GE/FE Switch with 10G Uplinks 16K entry MAC address table. General Descriptions 1K multicast group support. Broadcom s BCM53156XU is a family of highly integrated 128 KB packet buffer. Ethernet switches that are optimally designed for cost- srTCM and trTCM meters (support color aware and effective low-power applications in the SMB, Enterprise, color blind modes). Service-Provider, and SOHO markets that rapidly transition Eight CoS queues per port with priority flow-control. to Gigabit-Ethernet connectivity and beyond. IEEE 802.1p, MAC, and DSCP packet classification. Auto Loop detection. The BCM53156XU is based on the industry-leading 28 nm Auto DoS. RoboSwitch architecture, also known as Robo 2. The Auto VOIP. product line includes multiple models with 6 to 15 interfaces Auto QOS. that support 100M/1GE/2.5GE and 10GE of bandwidth. Auto IGMP snooping. The BCM53156XU is designed for standalone low port- 1K packets and bytes counters. count configurations and high port-count configurations with IEEE 802.3az Energy Efficient Ethernet (EEE). support for cascading. Jumbo frame support: up to 9728 bytes. 2 311-pin, 1313 mm FBGA package. The BCM53156XU allows customers to design complete product platforms that target new cost-effective low-power JTAG support. 2 applications demanding 1GE/10GbE connectivity. Among Includes one UART and MDIO interface, seven I C those, SMB switch with 10G uplinks, Enterprise switches, interfaces, and 9 GPIOs (via the MFIO). routers and security appliances, next generation Industrial Ethernet switches, and Service Provider access equipment. The BCM53156XU is also designed to support basic applications that include Auto DOS, Auto VOIP, Auto QoS, 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 Auto IGMP snooping as well as tools for monitoring and troubleshooting. The product line is offered in Commercial-grade as well as Industrial-grade temperature ranges. Features ARM Cortex-M7 at up to 400 MHz. Operational mode: Unmanaged. Up to 810/100/1000BASE-T ports with integrated ultra-low-power GPHYs. Up to 110G XFI with KR support. 1 RGMII. Switch cascading.
