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.
