Brief
8-PORT 10/100 SWITCH WITH ON-CHIP PACKET BUFFER
BCM5318 FEATURES
• ^{The world’s 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 Autocast^TM 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
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 cost-
sensitive unmanaged applications–providing 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.
