DM9000AEP Product Brief
Ethernet Controller with General Processor Interface
June 2008 Rev.1.0
Fast Ethernet 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 IO tolerance.
The DM9000A supports 8-bit and 16-bit data interfaces to internal memory accesses
for various processors. The PHY of the DM9000A can interface to the UTP3, 4, 5 in
10Base-T and UTP5 in 100Base-TX with
HP Auto-MDIX. It is fully compliant with the IEEE 802.3u Spec. Its auto-negotiation
function will automatically configure the DM9000A to take the maximum advantage
of its abilities. The DM9000A also supports IEEE 802.3x full- duplex flow control..
