BCM5380M

8FE+2GE PORT SWITCH WITH ON-CHIP PACKET BUFFER

S U M M A R Y O F B E N E F I T S

F E A T U R E S

The highest level of silicon integration achieved for an eight+two-port,

10/100/1000 Ethernet switch device

Enables a new generation of lower cost switches with gigabit

connectivity and much smaller form factors

•

Sixth-generation switch on a chip

•

Uses field-proven industry-standard

10BASE-T /100BASE-TX Fast Ethernet/100BASE-T

transceivers—lowers overall system interoperability and

reliability risks

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

Flexible interfaces support a wider variety of application

needs—SerDes, fiber for long distances or additional

100/1000TX ports

•

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

Provides the most cost-effective gigabit connectivity to the

desktop for all remote, branch, and home office needs

•

Cascadable to 24 Fast Ethernet + 6 Gigabit Ethernet ports through a

SerDes expansion port, 24FE + 2GE nonblocking

•

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

Packet classification 802.1p QoS priority queues

VLAN 4K 802.1Q or port-based supported

•

CPUs are not required to initialize and run in cost-sensitive

unmanaged applications, providing true Plug and Play

connectivity

•

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

•

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

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

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

On-chip HP auto-MDI/MDIX on all transceivers

automatically detects and corrects for crossover cables and

allows direct switch-to-switch connection

•

Management features:

•

Low-cost MIB Autocast™ function

Hardware support for simple network management protocol (SNMP),

remote network monitoring (RMON), and spanning tree

Scalable and Cost-Effective Solutions for 8+1 or 16+2 or 24+3 Port 10/100/1000 Unmanaged/Managed/Smart Switch

Optional ARM7

Management Module

Optional uP or EEPROM

Smart switch option
