C8051F33x-DK
6.5. Serial Interface (J5)
A RS232 transceiver circuit and DB-9 (J5) connector are provided on the target board to facilitate serial
connections to UART0 of the C8051F330. The TX, RX, RTS and CTS signals of UART0 may be connected to the
DB-9 connector and transceiver by installing shorting blocks on header J3.
6.6. Analog I/O (P2)
Several of the C8051F330 target device’s port pins are connected to the J6 terminal block. Refer to Table 4 for the
P2 terminal block connections.
6.7. IDAC Connector (J6)
The C8051F330 target board also features a Current-to-Voltage 1 KΩ load resistor that may be connected to the
10-bit current-mode Digital-to-Analog Converter (IDAC) on port pin (P0.1). Install a shorting block on J6 to connect
the IDAC pin of the target device to the load resistor. The IDAC signal is then routed to the J1[2] and P2[2]
connectors.
6.8. USB Debug Adapter Target Board Power Connector (J8)
The USB Debug Adapter includes a connection to provide power to the target board. This connection is routed
from J4[10] to J8[1]. Place a shorting block at header J8[2–3] to power the board directly from an ac/dc power
adapter. Place a shorting block at header J8[1–2] to power the board from the USB Debug Adapter. Please note
that the second option is not supported with either the EC1 or EC2 Serial Adapters.
