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...
