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 BCM5382M integrates:

• Eight 10/100 transceivers (802.3u compliant)

• Nine 10/100 media access controllers (802.x compliant)

• Two 10/100/1000 integrated switch 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 1G SerDes module

• Nonblocking 8 Fast Ethernet + 2 Gigabit Ethernet fully integrated switch

fabric

• 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

10/100/1000TX 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 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
