8FE+2GE PORT SWITCH WITH ON-CHIP PACKET BUFFER
FEATURES
SUMMARY OF BENEFITS
• ^{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
