DM9008F Product Brief
ISA/Plug & Play Super Ethernet Controller
June 2008 Rev.1.0
The DM9008 Ethernet controller is a highly integrated design that provides all
Medial Access Control (MAC) and Encode-Decode (ENDEC) functions in
accordance with the IEEE 802.3 standard. Network interfaces include 10BASE5 or
10BASE2 Ethernet via the AUI port and 10BASE-T via the Twisted-pair. The
DM9008 Ethernet controller can interface directly to the PC-AT ISA bus without any
external device. The interface to PC-AT ISA bus is fully compatible with NE2000
Ethernet adapter cards, so all software programs designed for NE2000 can run on the
DM9008 card without any modification.
Microsoft's Plug and Play and the jumperless software configuration function are both
supported. The capability of the PnP and Non-PnP mode auto-switch function allows
users to configure network card. No jumpers or switches are needed to set when using
either the PC or PnP function. The integrated 8Kx16 SRAM and 10BASE-T
transceiver make DM9008 more cost-effective.
