DM9008CEP Product Brief
Ethernet Controller with General Processor Interface
June 2008 Rev.1.0
The DM9008C is a fully integrated and cost-effective low pin count Ethernet
controller with a general processor interface, a Medial Access Control (MAC), a
10Base-T PHY and 16K Byte SRAM. It is designed with low power and high
performance process that support 3.3V with 5V IO tolerance.
The DM9008C supports 8-bit and 16-bit data interfaces to internal memory accesses
for various processors. The PHY of the DM9008C can interface to the UTP3, 4, 5 in
10Base-T with HP Auto-MDIX. It is fully compliant with the IEEE 802.3 Spec. Its
auto-negotiation function will automatically configure the DM9008C to take the
maximum advantage of its abilities. The DM9008C also supports IEEE 802.3x full-
duplex flow control...
