DM9000

ISA to Ethernet MAC Controller with Integrated 10/100 PHY

1. General Description

The DM9000 is a fully integrated and cost-effective

single chip Fast Ethernet MAC 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

tolerance.

The DM9000 also provides a MII interface to connect

HPNA device or other transceivers that support MII

interface. The DM9000 supports 8-bit, 16-bit and 32-

bit uP interfaces to internal memory accesses for

different processors. The PHY of the DM9000 can

interface to the UTP3, 4, 5 in 10Base-T and UTP5 in

100Base-TX. It is fully compliant with the IEEE 802.3u Spec.

Its auto-negotiation function will automatically configure the

DM9000 to take the maximum advantage of its abilities. The

DM9000 also supports IEEE 802.3x full- duplex flow control.

This programming of the DM9000 is very simple, so user

can port the software drivers to any system easily.
