DM9008F

Product Summary

The DM9008F Ethernet controller is a highly integrated ISA/Plug & Play Super Ethernet Contoller 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 DM9008F Ethernet controller can interface directly to the PC-AT ISA bus without any external device. The interface to PC-AT ISA bus of DM9008F is fully compatible with NE2000 Ethernet adapter cards, so all software programs designed for NE2000 can run on the DM9008 card without any modification.
