EIGHT-PORT 10/100 SWITCH WITH ON-CHIP PACKET BUFFER

FEATURES

SUMMARY OF BENEFITS

• The highest level of silicon integration achieved for a eight-

• Enables a new generation of lower cost 10/100 switches in

port 10/100 Ethernet switch device

much smaller form factors

• Fourth generation switch on a chip

• Utilizes field-proven industry-standard 10BASE-T/100BASE-

• The BCM5328M integrates:

• Eight transceivers (802.3u compliant)

• Nine media access controllers (802.x compliant)

• 256-KB packet buffer

• Non-blocking switch fabric

• Non-blocking up to 24 ports through a 2.6-Gbps expansion

port, cascading up to three devices

• Packet classification 802.1p QoS priority queues

• Port-based VLAN

• MII or 7-wire interface supports an additional 100FX or 100TX

connection enabling a sixth user connection or uplink

• Supports up to 4K MAC addresses

• Supports full-duplex (802.3x) and half-duplex options

• Supports automatic address learning and aging

TX Fast Ethernet transceivers—lowering overall system

interoperability and reliability risks

• Flexible interfaces support a wider variety of application

needs—fiber for long distances or an additional 100TX port

• Sufficient address range handles all remote office, branch

office and home office needs

• Port VLAN, trunking, and 802.1p priority enables the switch to

be designed into a wide variety of applications

• 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

• Internal oscillator circuit

• Low-cost management using the on-chip MIB registers allows

• Typical power consumption: < 1.8W

• 208-pin PQFP package

• Management features:

• Low-cost MIB AutocastTM function

• Hardware support for Simple Network Management Protocol

the collection and transmission of statistics for each port and

provides an upward migration path for corporate users

• On-chip HP auto-MDI/MDIX feature automatically detects and

corrects for crossover cables and allows direct switch-to-

switch connection

(SNMP), Remote Network Monitoring (RMON) and Spanning

Tree

Low Cost Managed 24-Port 10/100 Smart Switch
