Data Sheet BCM53128V Multiport Gigabit Ethernet Switches GENERAL DESCRIPTION FEATURES The Broadcom BCM53128V is a highly integrated, Nine 10/100/1000 media access controllers Seven port 10/100/1000BASE-T/Tx transceivers cost-effective unmanaged-smart gigabit switch. The One GMII/RGMII/MII/RvMII/TMII/RvTMII switch design is based on the field-proven, industry- interface for an in-band management port (IMP) leading ROBO architecture. This device combines all for connection to a CPU/management entity the functions of a high-speed switch system including without a PHY One GMII/RGMII/MII/RvMII/TMII/RvTMII packet buffers, PHY transceivers, media access interface of Port 7. controllers (MACs), address management, port- IEEE 802.1p, MAC, Port, ToS, and DiffServ QoS based rate control, and a nonblocking switch fabric for four queues, plus two time-sensitive queues into a single 65 nm CMOS device. Designed to be Port-based VLAN fully 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 BCM53128V provides compatibility with all Port-based rate control Port mirroring industry-standard Ethernet, Fast Ethernet, and BroadSync HD for IEEE 802.1AS support Gigabit Ethernet (GbE) devices. Timestamp tagging at MAC interface Time-aware egress scheduler The BCM53128V has a rich feature set suitable for DoS attack prevention not only standard GbE connectivity for desktop and Support for IPv6 laptop PCs, but also for next-generation gaming IGMP snooping, MLD snooping support consoles, set-top boxes, networked DVD players, and Green mode support home theater receivers. It is also specifically designed Spanning tree support (multiple spanning trees for next generation SOHO/SMB routers and up to eight) gateways. Loop detection for unmanaged configurations with Broadcoms patented LoopDTech technology The BCM53128V contains seven full-duplex 10/100/ CableChecker with unmanaged mode support 1000BASE-TX Ethernet transceivers. Double tagging/QinQ IEEE 802.az EEE (Energy Efficient Ethernet) In addition, the BCM53128V has one GMII/RGMII/ support MII/RvMII/TMII/RvTMII interface for a CPU or a router IEEE 802.3as support chip, providing flexible connectivity, as well as one IEEE 802.3x programmable per-port flow control GMII/RGMII/MII/RvMII/TMII/RvTMII interface for and backpressure, with IEEE 802.1X support for integrated gateways. secure user authentication EEPROM, MDC/MDIO, and SPI interfaces The BCM53128V provides 70+ on-chip MIB counters Serial flash Interface for accessing embedded 8051 processor to collect receive and transmit statistics for each port. 4K entry MAC address table with automatic learning and aging The BCM53128V is available in commercial 192 KB packet buffer temperature (C-Temp) and industrial temperature (I- 256 multicast group support Temp) rated packages. BCM53128V is provided in a Jumbo frame support up to 9720 bytes 256-pin eLQFP (28 mm 28 mm) package.
