The Broadcom BCM5380M device is a highly integrated solution. It
combines all of the functions of a high-speed switch system including
packet buffer, PHY transceivers, media access controllers, address
management, and a nonblocking switch fabric into a single 0.13-µm
CMOS device. It complies with the IEEE 802.3, 802.3u, 802.3ab 802.3x
specifications including the MAC control, pause frame, and auto-
negotiation subsections, providing compatibility with all industry-
standard Ethernet, and Fast Ethernet, and Gigabit Ethernet devices.
This device contains eight full-duplex 10BASE-T/100BASE-TX Fast
Ethernet transceivers and one 10/100/1000BASE-T transceiver, each of
which 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.
SPI or EEPROM interfaces provide easy programming of the 802.1p
QoS. This allows switch traffic to be given different classes of priority or
service—for example, voice traffic for IP phone applications, video
traffic for multimedia applications, or data traffic for e-mail applications.
Up to 4,000 VLANs can be set up via the SPI port.

Even though this device is primarily targeted for the cost-sensitive
unmanaged market, very low cost management can also be provided
utilizing the proprietary MIB Autocast function. MIB Autocast
encapsulates the on-chip MIB statistics and sends them out automatically
on a predefined port (or ports) at programmed intervals. This feature is
part of the 8051 micro smart-switch option for basic smart management
via a console port.
As part of the Smart Switch mode, the BCM5380M periodically
transmits Ethernet frames on a designated port. The frames can be
intercepted by an external management probe or a dedicated network
management application resident on any node within the network. In
addition, the ROBOSmartSwitch™ software provides system and port
configuration, VLAN and QoS setup, and IGMP snooping.
The BCM5380M is designed to work in Unmanaged Standalone or
Managed mode via the on-chip MII interface to an ARM7 CPU. This
provides support for the Ethernet-like MIB, bridge MIB, layer 2
management functions, private MIB, MIB II, and 4 groups of RMON.
