• The highest level of silicon integration achieved for an

8-Port 10/100 Ethernet switch device

• The world’s first single-chip switch

• The BCM5317 integrates:

• Eight transceivers (802.3u compliant)

• Nine media access controllers (802.x compliant)

• 256 KB packet buffer

• Non-blocking switch fabric

• 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: 2.7W

• 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

FEA TURES

8-Port Stand-Alone Unmanaged 10/100 Switch

• 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 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.
