Data Sheet BCM53115M Multiport Gigabit Ethernet Switches GENERAL DESCRIPTION FEATURES Seven 10/100/1000 media access controllers The Broadcom BCM53115M is a highly integrated, Five-port 10/100/1000 transceivers for Tx cost-effective smart-managed gigabit switch. The One GMII/RGMII/MII/RvMII/TMII interface for an switch design is based on the field-proven, industry- inband management port (IMP) for connection to a leading ROBO architecture. This device combines all CPU/management entity without PHY the functions of a high-speed switch system including One GMII/RGMII/MII/RvMII/TMII interface for WAN port packet buffers, PHY transceivers, media access Dual IMP ports support, WAN interface (Port 5) to controllers (MACs), address management, port-based be IMP port-capable rate control, and a non blocking switch fabric into a IEEE 802.1p, MAC Port, TOS, DiffServ QoS for four single 65 nm CMOS device. Designed to be fully queues, plus two time-sensitive queues Port-based VLAN compliant with the IEEE 802.3 and IEEE 802.3x IEEE 802.1Q-based VLAN with 4K entries specifications, including the MAC-control PAUSE MAC-based trunking with automatic link failover frame, the BCM53115M provides compatibility with Port-based rate control all industry-standard Ethernet, Fast Ethernet, and Port mirroring Compact field processor (CFP) Gigabit Ethernet (GbE) devices. 256 rules The BCM53115M has a rich feature set suitable for Filtering, classifications, remarking, and not only standard GbE connectivity for desktop and priority actions laptop PCs, but also for next-generation gaming Support IPv6 consoles, set-top boxes, networked DVD players, and Priority modification on egress home theater receivers. It is also specifically designed BroadSync HD for next-generation SOHO/SMB routers and Timestamp tagging at MAC interface gateways. Time-aware egress scheduler DOS attack prevention The BCM53115M contains five full-duplex 10/100/ Support IPv6 1000 BASE-TX Ethernet transceivers. In addition, the Ingress mirroring BCM53115M has one GMII/RGMII/MII/RvMII/TMII IGMP Snooping, MLD snooping support interface for the CPU or a router chip, providing Spanning tree support (multiple spanning treesup flexible 10/100/1000 Mbps connectivity. A GMII/ to eight) Loop detection for unmanaged configurations with RGMII/SGMII/MII/RvMII/TMII interface for the WAN Broadcoms patented LoopDTech technology port can be configured as an IMP port. CableChecker with unmanaged mode support Double tagging/QinQ The BCM53115M provides 70+ on-chip MIB counters Egress VID remarking to collect receive and transmit statistics for each port. IEEE802.3 as support IEEE 802.3x programmable per-port flow control The BCM53115M is available in industrial and backpressure, with IEEE 802.1x support for secure user authentication temperature (I-Temp) and commercial temperature EEPROM, MDC/MDIO, and SPI Interface (C-Temp) rated packages. The industrial-grade 4K entry MAC address table with automatic BCM53115M is provided in a 484-pin PBGA (23 mm x learning and aging 23 mm) package. The commercial-grade 128 KB packet buffer BCM53115M is provided in a 400-pin FBGA (17 mm x 128 multicast group support Jumbo frame support up to 9720 byte 17 mm) package. 1.2V for core and 3.3V for I/O JTAG support 484 PBGA 400 FBGA 53115M-DS12-R 5300 California Avenue Irvine, CA 92617 Phone: 949-926-5000 Fax: 949-926-5203 June 26, 2013BCM53115M Data Sheet Revision History Figure 1: Functional Block Diagram BCM53115M ContentAware 10/100/1000 Compact Field TRD 3:0 0 +/- (Port 0) GMAC PHY Processor 10/100/1000 TRD 3:0 1 +/- (Port 1) GMAC Register PHY Space 10/100/1000 TRD 3:0 2 +/- (Port2) GMAC PHY Packet Buffer MMU 10/100/1000 TRD 3:0 3 +/- (Port 3) GMAC PHY Address Management 10/100/1000 TRD 3:0 4 +/- (Port 4) GMAC PHY LED Interface LED GMAC GMII/RGMII/SGMII/MII/RvMII/TMII (Port 5) SGMII/SerDes EEPROM EEPROM GMII/RGMII/MII/RvMII/TMII Interface GMAC (IMP) BROADCOM Multiport Gigabit Ethernet Switches June 26, 2013 53115M-DS12-R Page 2 BROADCOM CONFIDENTIAL
