DM9000 General Description


  The DM9000 is a fully integrated and cost-effective single chip Fast Ethernet MAC 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 in100Base-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.
