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.
