BCM5325E
Enables a new generation of affordable five-port 10/100
switches with highest integration of enhanced L2+ features
Utilizes field-proven industry-standard 10BASE-T/100BASE-
TX (100BASE-FX-compatible) Fast Ethernet transceivers—
lowering overall system interoperability and reliability risks
802.1Q based VLAN and flexible priority queues mapped to
selectable protocols such as 802.1p, DiffServ, and COS,
enables the switch to be designed into a wide variety of
applications for multimedia and data traffic
Supports 802.1x for network security
WAN port allows one of the ports to be specified for WAN
connectivity, in which case all traffic coming to the WAN port
is forwarded to the CPU
Programmable per port storm provides better traffic
management
MII port supports additional 100TX/FX
Optional reversed MII port connects directly to an 802.3
compliant MAC
Access to all internal registers through SPI or MDC/MDIO
interfaces
Switch management features: Port statistic counters
