1. General Description
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 and it supports 3.3V and 5V signaling.
The DM9601 provides USB transceiver which is compliant
with USB1.1, 10/100M PHY, MAC controller, memory
controller and an external MII interface, to connect
HPNA device or other transceivers that support MII
interface. This chip already integrates into 16K byte
SRAM. The DM9601 has interfaces 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 DM9601 to take the maximum
advantage of its abilities. The DM9601 also supports 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.
