4.11 Fast Ethernet Network Controller
The DE2 board provides Ethernet support via the Davicom DM9000A Fast Ethernet controller chip.
The DM9000A includes a general processor interface, 16 Kbytes SRAM, a media access control
(MAC) unit, and a 10/100M PHY transceiver. Figure 4.18 shows the schematic for the Fast Ethernet
interface, and the associated pin assignments are listed in Table 4.12. For detailed information on
how to use the DM9000A refer to its datasheet and application note, which are available on the
manufacturer’s web site, and from the Datasheet folder on the DE2 System CD-ROM.
