Refer to Figure4 for the locations of the various I/O connectors.P1Power connector (accepts input from 7 to 15 VDC unregulated power adapter)J1 22-pin Expansion I/O connectorJ3 Port I/O Configuration Jumper BlockJ4 DEBUG connector for Debug Adapter interfaceJ5 DB-9 connector for UART0 RS232 interfaceJ6 Analog I/O terminal blockJ7 Connector for IDAC0 voltage circuitJ8 USB Debug Adapter target board power connectorJ9, J10 External crystal enable connectorsJ11 Connector for IDAC1 voltage circuitJ12 Connector block for Thermistor circuitryJ13, J14ADC external voltage reference connectorsFigure4.C8051F410 Target BoardC8051F41x4.1. System Clock SourcesThe C8051F410 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 191.4kHz (±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, if you wish to operate the C8051F410 device at a frequency not available with the internal oscillator, an external crystal may be used. Refer to the C8051F41x data sheet for more information on configuring the system clock source.The target board is designed to facilitate the installation of an external crystal. Remove shorting blocks at headers J9 and J18 and install the crystal at the pads marked Y2. Install a 10M resistor at R4 and install capacitors at C44 and C43 using values appropriate for the crystal you select. Refer to the C8051F41x data sheet for more information on the use of external oscillators. The target board also has a 32.768kHz watch crystal installed to provide a timebase for the smaRTClock. Jumper J26 may be used to short the XTAL3 and XTAL4 pins if internal clock mode is desired.4.2. Power OptionsThe C8051F41x Target Board has many power options. This allows the user to exercise the different operating modes of the C8051F410. The board has 2 voltage regulators. A 3.3V LDO and a 1.2–5.25V variable regulator. To use the 3.3V regulator, pin 2–3 of J9 should be shorted and a jumper installed in J10.To use the variable regulator, pin 1–2 of J19 should be shorted and an output voltage should be selected using J21. After selecting the appropriate voltage, pin 1–2 of J21 should be shorted to enable the output of the variable regulator. If the voltage "VAR" is selected, the potentiometer R23 should be adjusted until the desired voltage is reached. The input to the variable regulator can be obtained from the unregulated 9V supply or from the 5V USB VBUS supply available when using a USB debug adapter.Note: Before enabling either voltage regulator, the user should check the 4 supply rail selection headers (J29+J30, J17, J12, J31+32) to ensure the correct voltage is being routed to the correct power pin. An incorrect jumper setting may permanently damage the board. Note that VDD cannot exceed 2.5V and is typically derived from the on-chip regulator. Do not connect the 5.25 or 3.3V output directly to VDD.The three power LEDs for VIO, VREG, and VDD indicate if the appropriate supply rail is connected to a power supply. Check to make sure all supply rails (with exception of VREG if not using the on-chip regulator) are powered.For the VIO voltage rail, the user may choose from the 3V regulator (+3VD), the variable regulator, or the on-chip regulator. The selections are marked on the target board silkscreen.For the VREG on-chip voltage regulator input, the user may choose from the 3V regulator (+3VD), the 5V USB VBUS source obtained from the USB debug adapter (5VEC3), or from the variable regulator (VREG). The selections are marked on the target board silkscreen.For VDD, the user may choose the output of the on-chip regulator (VDD_) or the output of the variable regulator (VREG).4.3. Switches and LEDsThree switches are provided on the target board. Switch SW1 is connected to the RESET pin of the C8051F410. Pressing SW1 puts the device into its hardware-reset state. Switch SW2 and SW3 are connected to the C8051F410’s general purpose I/O (GPIO) pins through headers. Pressing SW2 or SW3 generates a logic low signal on the port pin. Remove the shorting block from the jumper J5 to disconnect SW2 and/or SW3 from their associated port pins. The port pin signals are also routed to pins on the J11 I/O connector. See Table1 for the port pins and headers corresponding to each switch.Three LEDs are also provided on the target board. The red LED labeled PWR is used to indicate a power connection to the target board. The green LEDs labeled with port pin names are connected to the C8051F410’s GPIO pins through headers. Remove the shorting blocks from the headers to disconnect the LEDs from the port pins. The port pin signals are also routed to pins on the J1 I/O connector. See Table1 for the port pins and headers corresponding to each LED.C8051F41xTable 1.

Evaluation C51 ‘C’ CompilerAn evaluation version of the Keil C51 ‘C’ compiler is included with the development kit and is installed during IDE installation. The evaluation version of the C51 compiler is the same as the full professional version except code size is limited to 4kB and the floating point library is not included. The C51 compiler reference manual can be found under the Help menu in the IDE or in the “SiLabs\MCU\hlp ” directory (C51.pdf).4.4. Using the Keil Software 8051 Tools with the Silicon Laboratories IDETo 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-51absolute 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 Applications Note AN104 - Integrating Keil 8051 Tools Into the Silicon Labs IDE in the “SiLabs\MCU\Documentation\Appnotes ” directory on the 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).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.)No tR e co mme nd edf or N e wDe si g n sC8051F00x/01x-DK4.4.1. Creating a New Project1.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 rec-ognized 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 filebrowser 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 targetbuild, 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. Right-click on “New Project” in the Project Window . Select Add Groups to project . Add pre-definedgroups 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.4.4.2. Building and Downloading the Program for Debugging1.Once all source files have been added to the target build, build the project by clicking on the Build/MakeProject 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 theConnection 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.C8051F00x/01x family devices use the JTAG 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 con-nect/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 Project As... from the menu. Create a new name for the project and click on Save .No tR e co mme nd edf or N e wDe si g n sC8051F00x/01x-DK5. Example Source CodeExample source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051F0xx ” 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.5.1. Register Definition FilesRegister definition files C8051F000.inc and C8051F000.h define all SFR registers and bit-addressable control/status bits for the C8051F00x/01x device family. They are installed into the “SiLabs\MCU\Examples\C8051F0xx ” directory during IDE installation. The register and bit names are identical to those used in the C8051F00x/01x 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.5.2. Blinking LED ExampleThe example source files blink.asm and blinky.c show examples of several basic C8051F00x/01x 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. When compiled/assembled and linked this pro-gram flashes the green LED on the target board about five times a second using the interrupt handler with a timer.No tR e co mme nd edf or N e wDe si g n sC8051F00x/01x-DK6. Target BoardThe C8051F00x/01x Development Kit includes a target board with a C8051F005 device pre-installed for evaluation and preliminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyp-ing using the target board. Refer to Figure 2 for the locations of the various I/O connectors.P1Power connector (accepts input from 7 to 15 VDC unregulated power adapter)J1Connects SW2 to port pin P1.7J264-pin I/O connector providing access to all I/O signals J3Connects LED D3 to port pin P1.6J4JTAG connector for Debug Adapter interface J6Analog I/O configuration connector X1Analog I/O terminal blockFigure 2. C8051F005 Target BoardNo tR e si g n sC8051F00x/01x-DK6.1. System Clock SourcesThe C8051F005 device installed on the target board features a internal oscillator which is enabled as the system clock source on reset. After reset, the internal oscillator operates at a frequency of 2MHz (±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 crystal may be installed on the target board for additional applications. The tar-get board is designed to facilitate the installation of an external crystal at the pads marked Q1. Refer to the C8051F005 datasheet for more information on configuring the system clock source. Following are a few part num-bers of suitable crystals:Freq (MHz)Digikey P/N ECS P/N18.432X146-ND ECS-184-20-1 (20pF loading capacitance)11.0592X089-ND ECS-110.5-20-1(20pF loading capacitance)6.2. Switches and LEDsTwo switches are provided on the target board. Switch SW1 is connected to the RESET pin of the C8051F005device on the target board. Pressing SW1 puts the device into its hardware-reset state. The device will leave the reset state after SW1 is released. Switch SW2 is connected to the device’s general purpose I/O (GPIO) pin through headers. Pressing SW2 generates a logic low signal on the port pin. Remove the shorting block from the header to disconnect SW2 from the port pins. The port pin signal is also routed to a pin on the J2 I/O connector. See Table 1 for the port pins and headers corresponding to each switch.Two LEDs are also provided on the target board. The red LED labeled PWR is used to indicate a power connection to the target board. The green LED labeled with a port pin name is connected to the device’s GPIO pin through a header. Remove the shorting block from the header to disconnect the LED from the port pin. The port pin signal is also routed to a pin on the J2 I/O connector. See Table 1 for the port pins and headers corresponding to each LED.6.3. Target Board JTAG Interface (J4)The JTAG connector (J4) provides access to the JTAG pins of the C8051F005. It is used to connect the Serial Adapter or the USB Debug Adapter to the target board for in-circuit debugging and Flash programming. Table 2 shows the JTAG pin definitions.Table 1.

Analog I/O (J6, Terminal Block)An Analog I/O Configuration connector (J6) provides the ability to route analog I/O signals from the C8051F005device to a terminal block by installing two shorting blocks on J6. It also allows the DAC outputs to be connected to Comparator 0 inputs or to two ADC inputs. Analog signals may be routed to the AIO 0 and AI01 posts of the termi-nal block by installing a shorting block between two adjacent pins on J6. Refer to Figure 3 to determine the shorting block installation positions required to connect the desired analog signal to the terminal block.

Expansion I/O Connector (J2)The 64-pin expansion I/O connector J1 provides access to most signal pins of the C8051F005 device on the target board. A small through-hole prototyping area is also provided. All I/O signals routed to connector J2 are also routed to through-hole connection points between J2 and the prototyping area (see Figure 4 on page 9). The signal layout pat-tern of these connection points is identical to the adjacent J2 connector pins .

C8051Fxxx软件配置说明
C8051Fxxx配置调试本文主要介绍在怎样在Keil μVision2环境下对C8051Fxxx进行调试。
结合一个工程介绍安装配置，以及说明怎么使用Keil μVision2进行调试。
一、安装配置用户在使用Keil μVision2 对C8051Fxxx单片机进行编程时，需要进行一定的安装配置，因为Keil μVision2本身没有这样的调试驱动。
首先安装Keil μVision2下的C8051F的驱动SiC8051F_uv2.exe(可以在压缩包里SiC8051F_uv2（2）.zip压缩吧包里面找到)。
然后对Keil μVision2进行软件配置：1、新建一个工程，选择Silicon Laboratories下面的C8051F021为CPU，如下图（如果是加载好的工程同样可以更改CPU和下面的设置）：2、单击Project\Options for Target ‘Target 1’选项，在出来的对话框中选择Target 选项，设置对应板卡上的晶振，这里是22.1184Mhz，如图如果需要下载Hex文件，则在Output选项中在Creat Hex File前面打对勾，否则去掉。
点击Debug选项，选择应用use Silicon Labs C8051Fxxx Drivers，选择Go till main。
如图：如果需要则在Setting中设置相应的端口和波特率。
由于使用是调试适配器用的是USB 口，且驱动是人体学输入设备，所以不用选择。
3、至此安装设置完成，可以使用Keil μVision2对C8051Fxxx系列单片机进行编写、编译、下载和运行程序。
二、相关操作1、编写程序在工程里面编写并添加程序，首先是新建一个C文件或者ASM文件：点击菜单栏中的file\new…打开编写程序的对话框，点击保存，弹出对话框进行保存，要编写成C文件后缀名为.C，如果是汇编语言则后缀名为.ASM，然后保存。
如下图：这就可以在文本对话框中进行程序编写了。

关于开发工具及调试的技术问答
1、问：C8051FXX系列单片机的开发工具是不是串行适配器（PC机串口和JTAG协议转换适配）相同而目标版不同？
答：开发套件中串行适配器（核心部件）是通用的，只是目标版不同。
只要您购买一套开发套件，就可以开发全系列单片机，只要将集成开发环境软件升级就可以了。
为了加快您的开发进程，您只要购买带有相关型号单片机的目标板就可以了。
2、问：C8051F单片机是怎样调试用户系统的？
答：C8051F单片机是用开发套件来调试用户系统的。
单片机开发套件包括开发软件IDE（集成开发环境），ML-EC3至PC机USB口和单片机JTAG接口的协议转换模块和一个目标板（板上有
C8051FMCU）。
IDE中集成编译器，汇编器和连接器，支持汇编语言和C语言（第三方支持）；ML-EC3是从USB口到JTAG协议的转换模块。
目标板上带有一块相应的C8051FMCU和一些简单的外围电路构成一个最小单片机系统，并将所有引脚连接到插座。
C8051F单片机内集成了一个以JTAG协议为基础的调试电路，这样在调试您的系统时，不需要专用仿真芯片、目标仿真头及目标RAM等。
您在IDE上编译生成程序代码后，通过ML-EC3（连接到计算机USB口和JTAG接口）将代码下载到用户系统板的C8051FMCU的Flash存储器中，然后您就可以调试您的目标系了。
3、问：可以用KeiluVision2IDE调试全系列C8051F单片机应用系统吗？
答：可以。
但必须安装动态链接库。
该驱动程序可以在我公司的网站上下载。
4、问：如何将绝对目标代码转换成hex格式文件？
答：第一，可以使用KEILC，在编译时直接生成。
第二，使用OH51（DOS命令）将目标文件转换成hex格式的文件。
Oh5Linputfile〔hexfile〕
第三，在IDE环境中生成HEX文件
﹙1﹚.在TOOL菜单中选择ADDREMOVEUSERTOOL
﹙2﹚.点击ADD按钮，增加一个MENUTEXT(名称可以任何输入)
﹙3﹚.在TOOLS里选择OH51.EXE文件（此文件在KEIL的BIN目录中有，必须将此文件放在项目所在目录）
﹙4﹚.在ARGUMENTS里输入文件名或项目名
﹙5﹚.在DIROF里输入HEX文件的保存目录
5、问：Silabs IDE中带有4K代码限制版的KeilC51,那么如何将无限制版的KeilC51嵌入到Silabs IDE中呢？
答：先将您完全版的KeilC51安装到您的PC机中；然后进入Silabs IDE界面，选择Project-﹥TOOLChainIntegration弹出对话框，单击Browse按钮，更换A51.EXE和BL51.EXE的路径（换成“Keil安装目录”/c51/bin）即可。
6、问：程序代码加密后，IDE不能与目标系统连接怎么办？
答：进入IDE界面，选择Tools→EraseSpace来擦除FLASH后，自动与目标系统连接。
