DM9000A series

The DM9000A is a fully integrated and cost-effectivelow pin count single chip Fast Ethernet controller witha general processor interface, a 10/100M PHY and 4KDword SRAM. It is designed with low power and highperformance process that support 3.3V with 5V IOtolerance.The DM9000A supports 8-bit and 16-bit datainterfaces to internal memory accesses for variousprocessors. The PHY of the DM9000A can interface to theUTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX withHP Auto-MDIX. It is fully compliant with the IEEE 802.3uSpec. Its auto-negotiation function will automaticallyconfigure the DM9000A to take the maximum advantage ofits abilities. The DM9000A also supports IEEE 802.3x full-duplex flow control.
