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.
P1 96-pin Expansion I/O connector
U1 CP2200 Ethernet Controller
J1 RJ-45 Ethernet Connector
SW1, SW2 Input Switches
LED1, LED2 Output LEDs
J4 Disconnects SW2 from P1
J3 Disconnects SW1 from P1
J5 Disconnects LED1 from P1
J6 Disconnects LED2 from P1
Figure 29. AB4 Ethernet Development Board
The AB4 Ethernet development board is compatible with multiple MCU development boards that contain a 96-pin
connector. Table 2 maps select signals on the AB4 board to the corresponding MCU port pin(s).
