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.
