8FE+2GE PORT SWITCH WITH ON-CHIP PACKET BUFFER
Scalable and Cost-Effective Solutions for 8+1 or 16+2 or 24+3 Port 10/100/1000 Unmanaged/Managed/Smart Switch

The highest level of silicon integration achieved for an eight+two-port,
10/100/1000 Ethernet switch device

Sixth-generation switch on a chip

The BCM5380M integrates:
Eight 10/100 transceivers (802.3u compliant)
Nine 10/100 media access controllers (802.x compliant)
Two 10/100/1000 media access controllers
One integrated 10/100/1000BASE-T/TX transceiver (802.3ab compliant)
256-KB packet buffer and 128-KB control memory
Nonblocking switch fabric
One integrated 1-Gbps SerDes module

Cascadable to 24 Fast Ethernet + 6 Gigabit Ethernet ports through a
SerDes expansion port, 24FE + 2GE nonblocking

Packet classification 802.1p QoS priority queues

VLAN 4K 802.1Q or port-based supported

Reverse MII, MII, or 7-wire interface supports an additional 100BASE-
FX or 100BASE-TX connection or uplink

Supports up to 4,000 unicast MAC addresses

Flow control: full-duplex (802.3x) and half-duplex options supported

Supports automatic address learning and aging

Internal oscillator circuit

Low power 0.13-µm 1.2V CMOS core: 3.5 W Pd.

324-pin FBGA package (small form factor 19 mm ∞ 19 mm)

Management features:
Low-cost MIB Autocast™ function
Hardware support for simple network management protocol (SNMP),
remote network monitoring (RMON), and spanning tree
Enables a new generation of lower cost switches with gigabit
connectivity and much smaller form factors
Uses field-proven industry-standard
10BASE-T /100BASE-TX Fast Ethernet/100BASE-T
transceivers—lowers overall system interoperability and
reliability risks
Flexible interfaces support a wider variety of application
needs—SerDes, fiber for long distances or additional
100/1000TX ports
Provides the most cost-effective gigabit connectivity to the
desktop for all remote, branch, and home office needs
802.1Q tag VLAN, trunking, and 802.1p priority enables the
switch to be designed into a wide variety of applications from
unmanaged to smart/managed switches
CPUs are not required to initialize and run in cost-sensitive
unmanaged applications, providing true Plug and Play
connectivity
Internal oscillator circuit simplifies design and reduces overall
system cost
Ability to gather and support basic management statistics with
only a very low-cost microcontroller
Low-cost management using the on-chip MIB registers allows
the collection and transmission of statistics for each port and
allows an upward migration path for corporate users
On-chip HP auto-MDI/MDIX on all transceivers
automatically detects and corrects for crossover cables and
allows direct switch-to-switch connection
