DM9010B

Single Chip Ethernet Controller with General Processor Interface

1. GENERAL DESCRIPTION

The DM9010B is a fully integrated and cost-effective

single chip Fast Ethernet MAC controller with a

general processor interface, a 10/100M PHY and 16K

Byte SRAM. It is designed with low power and high

performance process that support 3.3V with 5V

tolerance.

The DM9010B also provides a MII interface to connect

HPNA device or other transceivers that support MII

interface.

The DM9010B supports 8-bit, 16-bit and 32-bit uP

interfaces to internal memory accesses for different

processors. The PHY of the DM9010B 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 DM9010B to take

the maximum advantage of its abilities. The DM9010B also

supports IEEE 802.3x full- duplex flow control. This

programming of the DM9010B is very simple, so user can

port the software drivers to any system easily.
