C8051F38X DEVELOPMENT KIT USER’S GUIDE
1. Kit Contents
The C8051F38x Development Kit contains the following items:
C8051F380 Target Board
C8051Fxxx Development Kit Quick-Start Guide
AC to DC Power Adapter
USB Debug Adapter (USB to Debug Interface)
USB Cable
CD-ROM
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 DEBUG 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.
Use the Reset button in the IDE to reset the target when connected using a USB Debug Adapter.
Remove power from the target board before removing 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.
Figure 1. Hardware Setup Using a USB Debug Adapter
Note: The C8051F380 target board has the ability to be powered through the USB cable. To enable the USB-powered mode,
short the pins labeled VBUS and VREGIN on the J8 header. Do not short all 3 pins on the J8 header.

3. Software Setup
Simplicity Studio greatly reduces development time and complexity with Silicon Labs EFM32 and 8051 MCU
products by providing a high-powered IDE, tools for hardware configuration, and links to helpful resources, all in
one place.
Once Simplicity Studio is installed, the application itself can be used to install additional software and
documentation components to aid in the development and evaluation process.
The following Simplicity Studio components are required for the C8051F380 Development Kit:
8051 Products Part Support
Simplicity Developer Platform
Download and install Simplicity Studio from www.silabs.com/8bit-software or www.silabs.com/simplicity-studio.
Once installed, run Simplicity Studio by selecting St art
from the start menu or clicking the Simplicity Studio shortcut on the desktop. Follow the instructions to install the
software and click Simplicity IDE to launch the IDE.
The first time the project creation wizard runs, the Setup Environment wizard will guide the user through the
process of configuring the build tools and SDK selection.
In the Part Selection step of the wizard, select from the list of installed parts only the parts to use during
development. Choosing parts and families in this step affects the displayed or filtered parts in the later device
selection menus. Choose the C8051F38x family by checking the C8051F38x check box. Modify the part selection
at any time by accessing the Part Management dialog from the Window
Studio
Simplicity Studio can detect if certain toolchains are not activated. If the Licensing Helper is displayed after
completing the Setup Environment wizard, follow the instructions to activate the toolchain.

3.1. Running Blinky
Each project has its own source files, target configuration, SDK configuration, and build configurations such as the
Debug and Release build configurations. The IDE can be used to manage multiple projects in a collection called a
workspace. Workspace settings are applied globally to all projects within the workspace. This can include settings
such as key bindings, window preferences, and code style and formatting options. Project actions, such as build
and debug are context sensitive. For example, the user must select a project in the Project Explorer view in order
to build that project.
To create a project based on the Blinky example:
1. Click the Simplicity IDE tile from the Simplicity Studio home screen.
2. Click the Create new project link from the welcome screen or go to File
Project.
3. In the Kit drop-down, select C8051F380 Development Kit, in the Part drop-down, select C8051F380, and
in the SDK drop-down, select the desired SDK. Click Next.
4. Select Example and click Next.
5. Under C8051F380 Development Kit in the Blinky folder, select F38x Blinky and click Finish.
6. Click on the project in the Project Explorer and click Build, the hammer icon in the top bar. Alternatively,
go to Project
7. Click Debug to download the project to the hardware and start a debug session.
8. Press the Resume button to start the code running. The LED should blink.

9. Press the Suspend button to stop the code.
10. Press the Reset the device button to reset the target MCU.
11. Press the Disconnect button to return to the development perspective.
3.2. Simplicity Studio Help
Simplicity Studio includes detailed help information and device documentation within the tool. The help contains
descriptions for each dialog window. To view the documentation for a dialog, click the question mark icon in the
window:
This will open a pane specific to the dialog with additional details.
The documentation within the tool can also be viewed by going to Help
Help Contents or HelpSearch.

3.3. Legacy 8-bit IDE
Note: Using the Simplicity Studio tools with the C8051F380 Development Kit is recommended. See section 3. "Software
Setup‚" on page 2 for more information.
Download the 8-bit software from the website (www.silabs.com/8bit-software) or us e the provided installer on the
CD-ROM to install the software tools for the C8051F38x devices. After installation, examples can be found in
...\Examples\C8051F38x in the installation directory. At a minimum, the C8051F380 DK requires:
Silicon Labs IDE—Software enabling initial evaluation, development, and debugging.
Configuration Wizard 2—Initialization code generation software for the C8051F38x devices.
Keil C51 Tools—Keil 8051 Compiler/Assembler/Linker toolchain.
Other software available includes:
Keil µVision Driver—Driver for the Keil µVision IDE that enables development and debugging on
C8051Fxxx MCUs.
Flash Programming Utilities and MCU Production Programmer—Programming utilities for the
production line. More information on the available programming options can be found on the website:
http://www.silabs.com/products/mcu/Pages/ProgrammingOptions.aspx.
ToolStick Development Tools—Software and examples for the ToolStick development platform. More
information on this platform can be found at www.silabs.com/toolstick.
The development kit includes the latest version of the C51 Keil 8051 toolset. This toolset is initially limited to a code
size of 2 kB and programs start at code address 0x0800. After registration, the code size limit is removed entirely
and programs will start at code address 0x0000.
To register the Keil toolset:
1. Find the Product Serial Number printed on the CD-ROM. If you no longer have this serial number,
register on the Silicon Labs website (www.silabs.com/8bit-software) to obtain the serial number.
2. Open the Keil µVision4 IDE from the installation directory with administrative privileges.
3. Select File
License Management to open the License Management window.
