3.1. Software Installation
The included CD-ROM contains the Silicon Laboratories Integrated Development Environment (IDE), Keil software
8051 tools, and additional documentation. Insert the CD-ROM into your PC’s CD-ROM drive. An installer will
automatically launch, allowing you to install the IDE software or read documentation by clicking buttons on the
Installation Panel. If the installer does not automatically start when you insert the CD-ROM, run autorun.exe found
in the root directory of the CD-ROM. Refer to the ReleaseNotes.txt file on the CD-ROM for the latest information
regarding known problems and restrictions. After installing the software, see the following sections for information
regarding the software and running one of the demo applications.
3.2. CP210x USB to UART VCP Driver Installation
The C8051F580 Target Board includes a Silicon Laboratories CP2102 USB-to-UART Bridge Controller. Device
drivers for the CP2102 need to be installed before PC software such as HyperTerminal can communicate with the
target board over the USB connection. If the "Install CP210x Drivers" option is selected during installation, a driver
“unpacker” utility will launch.
1. Follow the steps to copy the driver files to the desired location. The default directory is C:\SiLabs\MCU\CP210x.
2. The final window will give an option to install the driver on the target system. Select the “Launch the CP210x VCP Driver
Installer” option if you are ready to install the driver.
3. If selected, the driver installer will now launch, providing an option to specify the driver installation location. After pressing
the “Install” button, the installer will search your system for copies of previously installed CP210x Virtual COM Port drivers. It
will let you know when your system is up to date. The driver files included in this installation have been certified by Microsoft.
4. If the “Launch the CP210x VCP Driver Installer” option was not selected in step 3, the installer can be found in the location
specified in step 2, by default C:\SiLabs\MCU\CP210x\Windows_2K_XP_S2K3_Vista. At this location, run
CP210xVCPInstaller.exe.
5. To complete the installation process, connect the included USB cable between the host computer and the USB connector
(P5) on the C8051F580 Target Board. Windows will automatically finish the driver installation. Information windows will pop
up from the taskbar to show the installation progress.
6. If needed, the driver files can be uninstalled by selecting “Silicon Laboratories CP210x USB to UART Bridge Driver
Removal” option in the “Add or Remove Programs” window.

4.2. Keil Evaluation Toolset
4.2.1. Keil Assembler and Linker
The assembler and linker that are part of the Keil Demonstration Toolset are the same versions that are found in
the full Keil Toolset. The complete assembler and linker reference manual can be found on-line under the Help
menu in the IDE or in the “SiLabs\MCU\hlp” directory (A51.pdf).
4.2.2. Keil Evaluation C51 C Compiler
The evaluation version of the C51 compiler is the same as the full version with these limitations: (1) Maximum 4 kB
code generation, and (2) Floating point library not included. When installed from the CD-ROM, the C51 compiler is
initially limited to a code size of 2 kB, and programs start at code address 0x0800. Please refer to the Application
Note “AN104: Integrating Keil Tools into the Silicon Labs IDE" for instructions to change the limitation to 4 kB, and
have the programs start at code address 0x0000.
4.3. Configuration Wizard 2
The Configuration Wizard 2 is a code generation tool for all of the Silicon Laboratories devices. Code is generated
through the use of dialog boxes for each of the device's peripherals.
Figure 1. Configuration Wizard 2 Utility
The Configuration Wizard 2 utility helps accelerate development by automatically generating initialization source
code to configure and enable the on-chip resources needed by most design projects. In just a few steps, the wizard
creates complete startup code for a specific Silicon Laboratories MCU. The program is configurable to provide the
output in C or assembly. For more information, please refer to the Configuration Wizard 2 help available under the

6. Using the Keil Software 8051 Tools with the Silicon Laboratories IDE
To perform source-level debugging with the IDE, you must configure the Keil 8051 tools to generate an absolute
object file in the OMF-51 format with object extensions and debug records enabled. You may build the OMF-51
absolute object file by calling the Keil 8051 tools at the command line (e.g., batch file or make file) or by using the
project manager built into the IDE. The default configuration when using the Silicon Laboratories IDE project
manager enables object extension and debug record generation.
Refer to Application Note "AN104: Integrating Keil
8051 Tools into the Silicon Labs IDE"
in the “SiLabs\MCU\Documentation\ApplicationNotes” directory 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).
The following sections illustrate the steps necessary to manually create a project with one or more source files,
build a program, and download the program to the target in preparation for debugging. (The IDE will automatically
create a single-file project using the currently open and active source file if you select Build/Make Project before a
project is defined.)
6.1. Creating a New Project
1. Select ProjectNew Project to open a new project and reset all configuration settings to default.
2. Select FileNew File to open an editor window. Create your source file(s) and save the file(s) with a
recognized extension, such as .c, .h, or .asm, to enable color syntax highlighting.
3. Right-click on “New Project” in the Project Window. Select Add files to project. Select files in the file
browser and click Open. Continue adding files until all project files have been added.
4. For each of the files in the Project Window that you want assembled, compiled, and linked into the target
build, right-click on the file name and select
Add file to build . Each file will be assembled or compiled as
appropriate (based on file extension) and linked into the build of the absolute object file.
Note: If a project contains a large number of files, the “Group” feature of the IDE can be used to organize
the files. Right-click on “New Project” in the
Project Window . Select Add groups to project . Add pre-
defined groups or add customized groups. Right-click on the group name and choose
Add file to group .
Select files to be added. Continue adding files until all project files have been added.

C8051F580DK

6.2. Building and Downloading the Program for Debugging
1. Once all source files have been added to the target build, build the project by clicking on the Build/Make
Project button in the toolbar or selecting ProjectBuild/Make Project from the menu.
Note: After the project has been built the first time, the Build/Make Project command will only build the
files that have been changed since the previous build. To rebuild all files and project dependencies, click
on the Rebuild All button in the toolbar or select ProjectRebuild All from the menu.
2. Before connecting to the target device, several connection options may need to be set. Open the
Connection Options window by selecting Options  Connection Options... in the IDE menu. First, select
the appropriate adapter in the “Serial Adapter” section. Next, the correct “Debug Interface” must be selected.
C8051F58x/59x family devices use the Silicon Labs 2-wire (C2) debug interface. Once all the selections are
made, click the OK button to close the window.
3. Click the
Connect button in the toolbar or select Debug  Connect from the menu to connect to the device.
4. Download the project to the target by clicking the Download Code button in the toolbar.
Note: To enable automatic downloading if the program build is successful, select Enable automatic
connect/download after build in the ProjectTarget Build Configuration dialog. If errors occur during
the build process, the IDE will not attempt the download.
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 Proj-
ect As... from the menu. Create a new name for the project and click on Save.
7. Example Source Code
Example source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051F58x_59x\”
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.
7.1. Register Definition Files
Register definition files C8051F580.inc and C8051F580_defs.h define all SFR registers and bit-addressable
control/status bits. A macro definition header file compiler_defs.h is also included, and is required to be able to use
the C8051F580_defs.h header file with various tool chains. These files are installed into the
“SiLabs\MCU\Examples\C8051F58x_59x\Header_Files\” directory during IDE installation by default. The register
and bit names are identical to those used in the C8051F58x/59x data sheet. These 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.
7.2. Blinking LED Example
The example source files F580_Blinky.asm and F580_Blinky.c installed in the default directory
“SiLabs\MCU\Examples\C8051F58x_59x\Blinky” show examples of several basic C8051F580 functions. These
include disabling the watchdog timer (WDT), configuring the Port I/O crossbar, configuring a timer for an interrupt
routine, initializing the system clock, and configuring a GPIO port pin. When compiled/assembled and linked, this
program flashes the green LED on the C8051F580 Target Board about five times a second using the interrupt
handler with a C8051F580 timer.

8.2. Target Board Power Options and Current Measurement (J7, J24, J31, P4)
The C8051F580 Target Board supports three power options:
1. 12V dc power using the ac to dc power adapter (P4)
2. 5V dc USB VBUS power from PC via the USB Debug Adapter (DEBUG_A)
3. 12V dc power from the LIN external header (TB1)
The two 12V power sources are ORed together using reverse-biased diodes (Z1 and Z2). The ORed power is
regulated to a 5.0V dc voltage using a LDO regulator (U6). To power the board from the USB Debug Adapter
connected to DEBUG_A instead of the 12V sources, move the shorting block on the J7 header to pins 1 and 2 to
select SER_PWR. The output of the regulator powers the +5VD net on the target board, and is also connected to
one end of the header J24 (Side A) and J31 (Side B). Two shorting blocks can be put on each header to connect
the 5V net to the VREGIN and VIO pins on the two MCUs. With the J19 shorting blocks removed, a source meter
can be used across the headers to measure the current consumption of the MCU.
Note: The USB Debug Adapter does not provide the necessary peak power for the CAN transceivers to operate. One of the
12V dc sources is recommended for CAN transceiver operation.
8.3. System Clock Sources (J9, J10)
8.3.1. Internal Oscillators
The C8051F580 and C8051F582 devices installed on the target board feature a factory-calibrated, programmable
high-frequency internal oscillator (24 MHz base frequency, ±0.5%), which is enabled as the system clock source on
reset. After reset, the internal oscillator operates at a frequency of 187.5 kHz by default but may be configured by
software to operate at other frequencies. The on-chip crystal is accurate for CAN and LIN master communications
and in many applications an external oscillator is not required. However, if you wish to operate the C8051F580
device (Side A) at a frequency not available with the internal oscillator, an external crystal may be used. Refer to
the C8051F58x/59x data sheet for more information on configuring the system clock source.
8.3.2. External Oscillator Options
The target board is designed to facilitate the installation of an external crystal. Remove shorting blocks at headers
J9 and J10 and install the crystal at the pads marked Y1. Install a 10 Mresistor at R2 and install capacitors at C6
and C7 using values appropriate for the crystal you select. If you wish to operate the external oscillator in capacitor
or RC mode, options to install a capacitor or an RC network are also available on the target board. R2, R3, C6, and
C7 are located on the back side of the board, near the Side A MCU. Populate C6 for capacitor mode, and populate
R3 and C6 for RC mode. Refer to the C8051F58x/59x data sheet for more information on the use of external
oscillators.
