BCM5325
FIVE-PORT 10/100 SWITCH WITH ON-CHIP PACKET BUFFER
Low Cost Five-Port 10/100 Stand-alone Switch
The highest level of silicon integration achieved for a five-port
10/100 Ethernet switch device
Fourth generation switch on a chip
The BCM5325 integrates:
Five transceivers (802.3u compliant)
Six media access controllers (802.x compliant)
128-KB packet buffer
Non-blocking switch fabric
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 2K MAC addresses
Flow control: full-duplex (802.3x) and half-duplex options
supported
Supports automatic address learning and aging
Internal oscillator circuit
Typical power consumption: < 1.4W
128-pin PQFP package
Enables a new generation of lower cost 10/100 switches in
much smaller form factors
Utilizes field-proven industry-standard 10BASE-T/100BASE-
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 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
On-chip HP auto-MDI/MDIX feature automatically detects and
corrects for crossover cables and allows direct switch-to-
switch connection
