EIGHT-PORT 10/100 SWITCH WITH ON-CHIP PACKET BUFFER
FEATURES
SUMMARY OF BENEFITS
⢠The highest level of silicon integration achieved for a eight-
port 10/100 Ethernet switch device
⢠Fourth generation switch on a chip
⢠The BCM5327M integrates:
⢠Eight transceivers (802.3u compliant)
⢠Nine media access controllers (802.x compliant)
⢠256-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 4K 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: < 1.8W
⢠208-pin PQFP package
⢠Management features:
⢠Low-cost MIB AutocastTM function
⢠Hardware support for Simple Network Management Protocol
(SNMP), Remote Network Monitoring (RMON) and Spanning
Tree
⢠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 transceiversâlowering overall system
interoperability and reliability risks
⢠Flexible interfaces support a wider variety of application
needsâfiber 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 applicationsâproviding 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
Low Cost Managed Eight-Port 10/100 Smart Switch
