DM9000EP Product Brief
Ethernet Controller with General Processor Interface
May 2008 Rev.1.0
controller with a general processor interface, a 10/100M PHY and 4K Dword SRAM. It is
designed with low power and high performance process that support 3.3V with 5V tolerance.
The DM9000 also provides a MII interface to connect HPNA device or other transceivers that
support MII interface. The DM9000 supports 8-bit, 16-bit and 32-bit uP interfaces to internal
memory accesses for different processors. The PHY of the DM9000 can interface to the
UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX. It is fully compliant with the IEEE 802.3u
Spec. Its auto-negotiation function will automatically configure the DM9000 to take the
maximum advantage of its abilities. The DM9000 also supports IEEE 802.3x full- duplex
flow control. This programming of the DM9000 is very simple, so user can port the software
drivers to any system easily.
