DM9000 series

The DM9000 is a fully integrated and cost-effectivesingle chip Fast Ethernet MAC controller with ageneral processor interface, a 10/100M PHY and 4KDword SRAM. It is designed with low power and highperformance process that support 3.3V with 5Vtolerance.The DM9000 also provides a MII interface to connectHPNA device or other transceivers that support MIIinterface. The DM9000 supports 8-bit, 16-bit and32-bit uP interfaces to internal memory accesses fordifferent processors. The PHY of the DM9000 caninterface 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 theDM9000 to take the maximum advantage of its abilities. TheDM9000 also supports IEEE 802.3x full- duplex flow control.This programming of the DM9000 is very simple, so usercan port the software drivers to any system easily.
