?The highest level of silicon integration achieved for a
5-port 10/100 Ethernet switch device
?The world’s first single-chip switch
?The BCM5315 integrates:
? Five transceivers (802.3u compliant)
? Six media access controllers (802.x compliant)
? 256 KB packet buffer
? Non-blocking switch fabric
? Non-blocking switch fabric through a 2.6-Gbps
expansion port, cascading up to three devices
?MII interface supports an additional 100FX or 100TX
connection enabling a sixth user port
? Supports up to 4K MAC addresses
? Flow control: full-duplex (802.3x) and half-duplex
options supported
? Supports automatic address learning and aging
?Typical power consumption: < 2.2W
? 208-pin PQFP package
?Optional management features:
? Low-cost MIB Autocast
TM
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
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.
? Flexible architecture enables high engineering leverage
when designing multiple platforms.
? CPUs are not required to initialize and run in costsensitive unmanaged applications–providing true
Plug and Play connectivity.
?Very low power and small footprint enables more costeffective system options.
?Ability to gather and support basic management
statistics using 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 allows 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.
