DM9016EP Product Brief
Three Port Ethernet Switch Controller with 8/16/32-bit
Processor Interface
March 2009 Rev.1.0
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.
