Davicom Semiconductor, Inc. 

DM9008C

Ethernet Controller with General Processor Interface

1. General Description

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...
