DM9010BI

Industrial-temperature Single Chip Ethernet Controller with General Processor Interface

Preliminary

Version: DM9010BI--DS-P01

January 12, 2010

1. GENERAL DESCRIPTION

The DM9010BI is a fully integrated and cost-effective

Industrial-temperature 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 DM9010BI also provides a MII interface to connect

HPNA device or other transceivers that support MII

interface.

The DM9010BI supports 8-bit, 16-bit and 32-bit uP

interfaces to internal memory accesses for different

processors. The PHY of the DM9010BI 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

DM9010BI to take the maximum advantage of its abilities.

The DM9010BI also supports IEEE 802.3x full- duplex flow

control. This programming of the DM9010BI is very simple,

so user can port the software drivers to any system easily.
