2. Hardware Setup using an EC2 Serial Adapter
Connect the target board to a PC running the Silicon Laboratories IDE via the Serial Adapter as shown in Figure 1.
1. Connect one end of the RS232 serial cable to a serial (COM) port on the PC.
2. Connect the other end of the RS232 serial cable to the DB-9 connector on the Serial Adapter.
3. Connect the Serial Adapter to the JTAG connector on the target board using the 10-pin ribbon cable.
4. Connect the AC/DC power adapter to power jack P1 on the target board.
Notes:
• Use the Reset button in the IDE to reset the target when connected using an EC2 Serial Adapter.
• Remove power from the target board and the EC2 before connecting or disconnecting the ribbon cable from
the target board. Connecting or disconnecting the cable when the devices have power can damage the
device and/or the EC2.

    C8051F12x-DK 3. Hardware Setup using a USB Debug Adapter The target board is connected to a PC running the Silicon Laboratories IDE via the USB Debug Adapter as shown in Figure 2. 1. Connect the USB Debug Adapter to the JTAG connector on the target board with the 10-pin ribbon cable.
  • Page 3 CD-ROM for additional information on using the Keil 8051 tools with the Silicon Laboratories IDE. To build an absolute object file using the Silicon Laboratories IDE project manager, you must first create a project. A project consists of a set of files, IDE configuration, debug views, and a target build configuration (list of files and tool configurations used as input to the assembler, compiler, and linker when building an output object file).

    They are installed into the “SiLabs\MCU\Examples\C8051F12x” directory during IDE installation. The register and bit names are identical to those used in the C8051F12x data sheet. Both register definition files are also installed in the default search path used by the Keil Software 8051 tools. Therefore, when using the Keil 8051 tools included with the development kit (A51, C51), it is not necessary to copy a register definition file to each project’s file directory.

  • Page 5: Target Board

    C8051F12x-DK 7. Target Board The C8051F12x Development Kit includes a target board with a C8051F120 device pre-installed for evaluation and preliminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyping using the target board. Refer to Figure 3 for the locations of the various I/O connectors.

    3.0625MHz (+/-2%) by default but may be configured by software to operate at other frequencies. Therefore, in many applications an external oscillator is not required. However, an external 22.1184 MHz crystal is installed on the target board for additional applications. Refer to the C8051F12x data sheet for more information on configuring the system clock source.
  • Page 7 C8051F12x-DK 7.4. Serial Interface (J5) A RS232 transceiver circuit and DB-9 (J5) connector are provided on the target board to facilitate serial connec- tions to UART0 of the C8051F120. The TX, RX, RTS and CTS signals of UART0 may be connected to the DB-9 connector and transceiver by installing shorting blocks on headers J6, J8, J9 and J10.
  • Page 8 C8051F12x-DK 7.6. PORT I/O Connectors (J12 - J19) In addition to all port I/O signals being routed to the 96-pin expansion connector, each of the eight parallel ports of the C8051F120 has its own 10-pin header connector. Each connector provides a pin for the corresponding port pins 0-7, +3.3 VDC and digital ground.
  • Page 9 C8051F12x-DK 7.8. Expansion I/O Connector (J24) The 96-pin expansion I/O connector J24 is used to connect daughter boards to the main target board. J24 provides access to many C8051F120 signal pins. Pins for +3 V, digital ground, analog ground and the unregulated power supply (VUNREG) are also available.

    10-pin connector on the Serial Adapter labeled “DEBUG”, see Figure 5. (The Serial Adapter sup- ports both Silicon Laboratories JTAG and C2 debug interfaces.). All Serial Adapters may be powered from the tar- get board, but the EC1 and EC2 Serial Adapter units cannot provide power to the target board. Table 7 shows the pin definitions for the Serial Adapter’s DEBUG connector.

  • Page 11: Usb Debug Adapter

    C8051F12x-DK 9. USB Debug Adapter The USB Debug Adapter provides the interface between the PC’s USB port and the C8051F12x’s in-system debug/programming circuitry. The attached 10-pin DEBUG ribbon cable connects the adapter to the target board and the target device’s debug interface signals. (The USB Debug Adapter supports both Silicon Laboratories JTAG and C2 debug interfaces.) Power is provided to the adapter from the USB connection to the PC.
