GENERAL DESCRIPTION
The MU9C8358, when configured with MUSIC Semiconductors MU9Cx480A family of LANCAMs, provides a high performance, large capacity Ethernet address processing subsystem for use in Ethernet bridge, switch, or remote access products. The device is designed to work in multi-port systems that require a common address database for all ports. Built-in arbitration allows two MU9C8358 devices to share a common CAM database, supporting up to eight 100Mb/s Ethernet ports at wire speed.

DISTINCTIVE CHARACTERISTICS
• Four industry-standard 10/100Mb MII ports
• Supports station list up to 16K addresses
• Built-in arbitration supports eight 100Mb Ethernet ports
• Port ID identification and MAC Frame Reject signal based on DA search results
• Read search results from the Result port or CPU port
• Hardware support for Tag switching
• Optional automatic learning of new SAs
• Optional automatic Aging and Purging
• 208-pin PQFP package
• 5 Volt operation
