DM9010BEP Product Brief

Ethernet Controller with General Processor Interface

June 2008 Rev.1.0

The DM9010B 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 DM9010B also provides a MII interface to connect HPNA device or other

transceivers that support MII interface.

The DM9010B supports 8-bit, 16-bit and 32-bit uP interfaces to internal memory

accesses for different processors. The PHY of the DM9010B 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 DM9010B

to take the maximum advantage of its abilities. The DM9010B also supports IEEE

802.3x full- duplex flow control. This programming of the DM9010B is very simple,

so user can port the software drivers to any system easily.
