1. Kit Contents
The C8051F04x Development Kit contains the following items:
• Two C8051F040 Target Boards
• C8051Fxxx Development Kit Quick-Start Guide
• Silicon Laboratories IDE and Product Information CD-ROM. CD content includes:
• Silicon Laboratories Integrated Development Environment (IDE)
• Keil 8051 Development Tools (macro assembler, linker, evaluation 'C' compiler)
• Source code examples and register definition files
• Documentation
• C8051F04x Development Kit User's Guide (this document)
• Two AC to DC Power Adapters
• CAN Cable (DB-9 connectors)
• USB Debug Adapter (USB to Debug Interface)
• USB Cable
2. 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 1.
1. Connect the USB Debug Adapter to the JTAG connector on the target board with the 10-pin ribbon cable.
2. Connect one end of the USB cable to the USB connector on the USB Debug Adapter.
3. Connect the other end of the USB cable to a USB Port on the PC.
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 a USB Debug Adapter.
• Remove power from the target board and the USB Debug Adapter 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 USB Debug Adapter.

Page 2: Software Setup
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). - Page 3 5. Save the project when finished with the debug session to preserve the current target build configuration, editor settings and the location of all open debug views. To save the project, select Project->Save Project As... from the menu. Create a new name for the project and click on Save. C8051F04x-DK → Build/Make Project from the menu.
- Page 4 C8051F04x-DK 5. Example Source Code Example source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051F04x” directory during IDE installation. These files may be used as a template for code development. Example applications include a blinking LED example which configures the green LED on the target board to blink at a fixed rate. A Controller Area Network (CAN) application example is also included with the C8051F04x development kit.
- Page 5 CD-ROM. Accessing the CAN controller (i.e., accessing the CAN RAM, CAN registers, and moving data to and from the CAN controller) is documented in Silicon Laboratories’ C8051F04x data sheet. An example CAN application is included in the “Examples\C8051F04x” directory. Each C8051F040 target board fea- tures a push button (labeled P3.7) and a LED (labeled P1.6).

C8051F04x-DK 6.1. System Clock Sources The C8051F040 device installed on the target board features a calibrated programmable internal oscillator which is enabled as the system clock source on reset. After reset, the internal oscillator operates at a frequency of 3.0625 MHz (±2%) by default but may be configured by software to operate at other frequencies. Therefore, in many applications an external oscillator is not required. - Page 9 Table 4 for J11 pin definitions. Table 3. J20 Terminal Block Pin Descriptions Table 4.

In addi- tion, when a shorting block is installed on header J7, writing a logic 'high' to port pin P4.2 will place the CAN trans- ceiver in low-current standby mode.
