DM9013
3-port switch with Processor Interface
1. 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.
