BCM5325M
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
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
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

... This function requires only a small, low-cost microcontroller to initialize and configure the device. The BCM5325M provides an on-chip MIB statistics register to collect, receive, and transmit statistics for each port. Additionally it provides direct hardware support for the EtherLike MIB, Bridge MIB, MIB II (interfaces) and the first four groups of the RMON MIB ...
