DM9010EP Product Brief
Ethernet Controller with General Processor Interface
June 2008 Rev.1.0
The DM9010 is a fully integrated and cost-effective single chip Fast Ethernet MAC
controller with a general processor interface, a 10/100M PHY and 16K Byte SRAM.
It is designed with low power and high performance process that support 3.3V with
5V tolerance.
The DM9010 also provides a MII interface to connect HPNA device or other
transceivers that support MII interface. The DM9010 supports 8-bit, 16-bit and 32-bit
uP interfaces to internal memory accesses for different processors. The PHY of the
DM9010 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 DM9010 to take the maximum advantage of its abilities.
The DM9010 also supports IEEE 802.3x full- duplex flow control. This programming
of the DM9010 is very simple, so user can port the software drivers to any system
easily.
