The BCM53212M is a ninth generation RoboSwitch™ design based on
the field-proven BCM5320 device. This integrated 0.13µ-CMOS device
combines all the functions of a high-speed switch system including
packet buffers, PHY transceivers, Media Access Controllers (MACs),
address management, and a non-blocking switch fabric. It is designed to
be fully compliant with the IEEE 802.3 and IEEE 802.3x specifications,
including the MAC control pause frame, auto-negotiation and with all
industry standard Ethernet and Fast Ethernet devices.
The BCM53212M contains 16 full-duplex 10BASE-T/100BASE-TX
Fast Ethernet transceivers with advanced cable diagnostics support. Each
performs all of the physical layer interface functions for 10BASE-T
Ethernet on Category 3, 4, or 5 Unshielded Twisted Pair (UTP) cable and
100BASE-TX Fast Ethernet on category 5 UTP cable. In addition, the
BCM53212M has two GMII/RGMII/TBI interfaces that provide flexible

The BCM53212M has a rich feature set suitable for streaming VoIP,
video and data traffic for multimedia applications. The BCM53212M
supports up to four QoS queues per port. Traffic QoS can be assigned
based on Port-ID, MAC address, 802.1p or DiffServ. Together with 4K
entries, 802.1Q VLAN, 802.1x EAPOL protocol filtering, MAC-based
link aggregation with dynamic failover, per-port bandwidth/rate control,
MAC address locking, and IGMP/MLD snooping at Layer 3 allow
system vendors to build advanced L2+ switch systems for the Multi-
Tenant/Multi-Dweller Unit (MTU/MDU) markets. The BCM53212M
provides 70+ on-chip MIB counters to collect receive and transmit
statistics for each port.
