5.11 Fast Ethernet Network Controller

The DE2-70 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 5.17 shows the schematic for the Fast
Ethernet interface, and the associated pin assignments are listed in Table 5.15. 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, or in the Datasheet/Ethernet folder on the DE2-70
System CD-ROM.
