BCM5317 PRODUCT Brief ® 8 - P O RT 1 0 / 1 0 0 S W I T C H W I T H O N - C H I P PA C K E T B U F F E R B C M 5 3 1 7 S U M M A R Y F E AT U R E S • 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 O F B E N E F I T S 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. 8-Port Stand-Alone Unmanaged 10/100 Switch BROADCOM PROPRIETARY & CONFIDENTIAL
