General Description

The DM9013 is a fully integrated and cost-effective fast Ethernet switch controller with two ports 10M/100M PHY, one port MII or RMII or Reverse MII interface, and general processor bus interface. The controller provides basic Layer-2 switch functions and advanced IEEE 802.1Q VLAN and priority queuing scheme. The integrated two ports PHY are compliant with IEEE 802.3u standards. The MII interface provides the flexibility to connect Ethernet PHY or SoC with MII/RMII interface. The DM9013 provides direct interface to the general processor bus with 8-, 16-, or 32-bit data to access internal memory.
