DM9601E Product Brief

USB to Ethernet MAC Controller with Integrated 10/100 PHY

June 2008 Rev.1.0

The DM9601 is a fully integrated and cost-effective single chip USB to Fast

Ethernet MAC controller with 10/100 PHY. It is designed with the low power and

high performance process. It is a 3.3V device with 5V tolerance then it supports 3.3V

and 5V signaling.

The DM9601 provides USB transceiver compliant with USB1.1, 10/100M PHY,

MAC controller, memory controller and an external MII interface to connect HPNA

device or other support MII interface transceiver. This chip already integrated 16K

byte SRAM. The DM9601 interfaces to the UTP3, 4, 5 in 10Base-T and UTP5 in

100Base-TX. It is fully compliance with the IEEE 802.3u Spec. Its auto-negotiation

function will automatically configure the DM9601 to take the maximum advantage of

its abilities. The DM9601 is also support IEEE 802.3x full-duplex flow control.

The DM9601 supports 3 wake-up event to wake-up system from suspend mode.

There are 7 GPIO pins (General purpose I/O) for user’s application.
