DM9010
Single Chip Ethernet Controller with General Processor Interface
1. General Description
The DM9010 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.
different processors. The PHY of the DM9010 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
DM9010 to take the maximum advantage of its abilities. The
DM9010 also supports IEEE 802.3x full- duplex flow control.
This programming of the DM9010 is very simple, so user
can port the software drivers to any system easily.
The DM9010 also provides a MII interface to connect
HPNA device or other transceivers that support MII
interface. The DM9010 supports 8-bit, 16-bit and
32-bit uP interfaces to internal memory accesses for
