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 Autocast^TM 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
