2014/2/18

General Description

The DM9051 is a fully integrated and cost-effective

low pin count single chip Fast Ethernet controller with

SPI interface, a 10/100M PHY and 4K Dword SRAM.

It is designed with low power and high performance

SPI interface that support 5V/3.3V IO tolerance.

The DM9051 supports SPI interfaces to internal

memory accesses for various processors. The PHY of

the DM9051 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 DM9051 to take the maximum advantage of

its abilities. The DM9051 also supports IEEE 802.3x full-

duplex flow control.
