Three Port Ethernet Switch Controller with 8/16/32-bit

The DM9016 is a fully integrated and cost-effective fast Ethernet switch controller with two ports 10M/100M PHY, one port MII/RMII/Reverse MII interface, and local bus interface. The controller provides basic Layer-2 switch functions and advance IEEE 802.1Q VLAN, priority queuing scheme, IGMP snooping protocol. The integrated two ports PHY are compliant with IEEE 802.3u standards. The MII/RMII/Reverse MII interface provides the flexibility to connect Ethernet 10/100M PHY devices. The DM9016 provides direct interface to the local bus.
