Brief
8-PORT 10/100 SWITCH WITH ON-CHIP PACKET BUFFER
BCM5318 FEATURES
⢠The worldâs first single-chip switch
⢠The highest level of silicon integration achieved for an
8-port 10/100 Ethernet switch device:
⢠Eight transceivers (802.3u compliant)
⢠Nine media access controllers (802.x compliant)
⢠256 KB packet buffer
⢠Non-blocking switch fabric
⢠Non-blocking up to 24 ports through a 2.6-Gbps
expansion port, cascading up to three devices
⢠MII interface supports an additional 100FX or 100TX
connection, enabling a ninth 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: 2.8W
⢠208-pin PQFP package
⢠Optional management features:
⢠Low-cost MIB AutocastTM function
⢠Hardware support for Simple Network Management
Protocol (SNMP), Remote Network Monitoring (RMON)
and Spanning Tree
SUMMARY OF BENEFITS
⢠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.
⢠Flexible architecture enables high engineering leverage
when designing multiple platforms.
⢠CPUs are not required to initialize and run in cost-
sensitive unmanaged applicationsâproviding true
Plug and Play connectivity.
⢠Very low power and small footprint enables more cost-
effective system options.
⢠Ability to gather and support basic management
statistics with only a very low-cost microcontroller.
⢠Low-cost management via 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.
