9. AB4 Ethernet Development Board
The Embedded Ethernet Development Kit includes the AB4 Ethernet Development Board designed to connect the
C8051F120 (or C8051F340, C8051F020, C8051F040, or C8051F060) target board to an ethernet network. The
ethernet controller used is the CP2200. Refer to Figure 29 for the locations of the various I/O connectors.
