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.

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.

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
