Preliminary Data Sheet BCM53101M Six-/Seven-Port Managed 10/100 Ehternet Switches GENERAL DESCRIPTION FEATURES The Broadcom BCM53101M is a highly Six 10/100 media access controllers integrated, cost-effective seven-port 10/100BASE- One 10/100/1000 media access controller T/TX managed switch. The switch design is based Five-port 10/100 transceivers for TX on the field-proven, industry-leading ROBO One RGMII/MII/RvMII/RMII/TMII/RvTMII interface for an inband management port (IMP) for connection architecture. This device combines all the to a CPU/management entity without PHY functions of a high-speed switch system including One MII/RvMII/RMII/TMII/RvTMII interface for a packet buffers, PHY transceivers, media access WAN port controllers (MACs), address management, port- Dual IMP ports support, WAN port to be IMP port- based rate control, and a non-blocking switch capable fabric into a single 65 nm CMOS device. Designed IEEE 802.1p, MAC Port, TOS, and DiffServ QoS for four queues, plus two time-sensitive queues to be fully compliant with the IEEE 802.3 and IEEE Port-based VLAN 802.3x specifications, including the MAC-control VLAN-based ingress rate limit: 64 kbps granularity PAUSE frame, the BCM53101M provides IEEE 802.1Q-based VLAN with 4K entries compatibility with all industry-standard Ethernet Port-based ingress rate control and egress rate and fast Ethernet devices. shaping with 64 kbps granularity MAC-based trunking with automatic link failover The BCM53101M has a rich feature set suitable for Protected port applications not only for next-generation cable, Broadcast storm control - per port based xDSL and EPON/GPON gateways, but also for Port mirroring and storm suppression SOHO/SMB routers. It is also specifically designed BroadSync HD for next generation set-top boxes. Timestamp tagging at MAC interface Time-aware egress scheduler The BCM53101M contains five full-duplex 10/100 IGMP Snooping, MLD snooping support BASE-TX Ethernet transceivers. In addition, the Spanning tree support (802.1D/1s/1w) BCM53101M has one RGMII/MII/RvMII/RMII/ - Multiple Spanning treesup to eight TMII/RvTMII interface for the CPU or a router chip, Double-tagging tolerant providing flexible 10/100/1000 Mbps connectivity. IEEE 802.3as support There is another MII/RvMII/RMII/TMII/RvTMII IEEE 802.3x programmable per port flow control and interface for the WAN port or configurable as the back pressure dual IMP port. IEEE 802.1x support for secure user authentication EEPROM, MDC/MDIO, and SPI interface The BCM53101M provides 70+ on-chip MIB Parallel/serial LED support counters to collect receive and transmit statistics 2K entry MAC address table with automatic learning for each port. and aging 64 KB packet buffer The BCM53101M is available in industrial 128 multicast group support temperature (I-Temp) and commercial Maximum frame size support up to 9720 bytes temperature (C-Temp) rated packages. 1.2V for core and 2.5V/3.3V for I/O Trap reserved multicast MAC addresses to IMP port JTAG support 132-pin DRQFN package (10 mm x 10 mm) 53101M-DS05-R 5300 California Avenue Irvine, CA 92617 Phone: 949-926-5000 Fax: 949-926-5203 December 2, 2011 Broadcom ConfidentialBCM53101M Preliminary Data Sheet Revision History BCM53101M 10/100 TRD 3:0 0 +/- MAC PHY 10/100 TRD 3:0 1 +/- MAC Register PHY Space 10/100 TRD 3:0 2 +/- MAC PHY Packet Buffer MMU 10/100 MAC TRD 3:0 3 +/- PHY Address Management 10/100 MAC TRD 3:0 4 +/- PHY LED Interface LED GMAC RGMII/MII/RvMII/RMII/TMII/RvTMII (IMP0, Port 8, MII 1) EEPROM EEPROM MII/RvMII/RMII/TMII/RvTMII (IMP1, Port 5, MII 2) MAC Interface Figure 1: BCM53101M Functional Block Diagram BROADCOM December 2, 2011 53101M-DS05-R Page 2 Broadcom Confidential
