The DM9000 is a fully integrated and
cost-effective single chip Fast Ethernet MAC controller
with a general processor interface, a 10/100M PHY and 4K
Dword SRAM. It is designed with the low power and high
performance process that support 3.3V with 5V tolerance.
The DM9000 also provides a MII
interface to connect HPNA device or other support MII
interface transceiver. The DM9000 support 8-bit, 16-bit
and 32-bit uP interface to internal memory accesses for
different processors. The PHY of the DM9000 can
interface 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 DM9000 to take the maximum advantage of
its abilities. The DM9000 is also support IEEE 802.3x
full-duplex flow control. This programming of the DM9000
is very simple, so user can port the software drivers to
any system easily. |
