The DM9000C/CI is a industrial-temperature fully

integrated and cost-effective low pin count single chip

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 interface that support 3.3V with 5V IO


The DM9000C/CI supports 8-bit and 16-bit data

interfaces to internal memory accesses for various

processors. The PHY of the DM9000C/CI 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 DM9000C/CI to take the maximum advantage

of its abilities. The DM9000C/CI also supports IEEE 802.3x

full- duplex flow control.
