Refer to Figure4 for the locations of the various I/O connectors.P1Power connector (accepts input from 7 to 15 VDC unregulated power adapter)J134-pin Expansion I/O connectorJ3Port I/O Configuration HeaderJ4DEBUG connector for Debug Adapter interfaceJ5DB-9 connector for UART0 RS232 interfaceJ6Analog I/O terminal blockJ7Low pass filter connectorJ9, J10External crystal enable connectorsFigure4.C8051F300 Target BoardC8051F30x4.1. System Clock SourcesThe C8051F300 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 3.0625MHz (+/-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, if you wish to operate the C8051F300 device at a frequency not available with the internal oscillator, an external crystal may be used. Refer to the C8051F30x 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 resistors R7 and R8 and install the crystal at the pads marked Y1. Install a 10M resistor at R9 and install capacitors at C14 and C15 using values appropriate for the crystal you select. Refer to the C8051F30x data sheet for more information on the use of external oscillators.4.2. Switches and LEDsTwo switches are provided on the target board. Switch SW1 is connected to the RESET pin of the C8051F300. Pressing SW1 puts the device into its hardware-reset state.

由于单片机是一门理论性和实用性都很强的技术，多数学员从未接触过，而且学习时间短、练习时间不足，所以长期以来这门课程的通过率都比较低。
特别是实操，更是学员们获取职业资格证书的“拦路虎”。
更有甚者，高昂的考试费用，让部分学员在经历多次考试未通过后，不得不放弃，在自己的人生中留下遗憾。
所谓“实操”，主要就是考查学员们的实际操作能力。
实践已经证明，多操多练才是掌握所学内容、顺利通过考试的唯一捷径。
然而培训机构安排的实操练习时间不仅非常有限，而且不一定合理。
比如，实操课上完一段时间后才有考试机会，这时多数学员可能都已将所学内容忘记得差不多了。
所以很多学员自己购买仿真器和元件，在家中或单位反复练习，特别是考前进行突击复习。
但是目前市面上能买到的、能全部完成高电和技师考试各十个实验题目的仿真器，价格都在数百元以上，对学员们来说，这是一笔不小的经济负担。
而且市面上仿真器种类繁多，鱼龙混杂，很有可能买到伪劣或不适用的产品。
深圳旗峰电子应广大学员们要求，在经过广泛调查的基础上，结合本公司技术研发力量，在资深培训教师的指导下，开发出这款“高电/技师单片机课程专用仿真器”，填补了市场上的空白。
本仿真器具有如下特点：1.专为学员设计，经测试能完成高电实操要求的全部十个实验和技师实操要求的全部十个实验的仿真。

Silicon Laboratories C8051F系列FLASH安全用户指南说明书
Rev. 1.1 12/03Copyright © 2003 by Silicon LaboratoriesAN1201. Relevant DevicesThis application note applies to the following devices:C8051F000, C8051F001, C8051F002, C8051F005,C8051F006, C8051F010, C8051F011, C8051F012,C8051F015, C8051F016, C8051F017, C8051F206,C8051F220, C8051F221, C8051F226, C8051F230,C8051F231, and C8051F236.IntroductionSilicon Labs Integrated Devices feature in-system programmable FLASH memory for convenient,upgradable code storage. The FLASH may be pro-grammed via the JTAG interface or by application code for maximum flexibility. Proprietary informa-tion in the form of code and constants are often stored in FLASH memory. Silicon Labs provides security options at the disposal of the designer to prevent unauthorized access to information stored in FLASH memory.Silicon Labs integrated devices provide FLASHsecurity options to:1.Prevent unauthorized access of intellectualproperty in the form of code and constants stored in FLASH.2.Prevent inadvertent modification of code by the end-user.3.Prevent code modification due to abnormal sys-tem conditions (e.g., low-voltage supply condi-tions to the device).Silicon Labs devices offer security options to pre-vent unauthorized access of the FLASH via the JTAG port and application software loaded by the end-user. FLASH Program Memory Security Bytes are used to prevent access via the JTAG interface,and a Software Read Limit (available on most Sili-con Labs devices) is to prevent unauthorized accessthrough application software. This application notediscusses the operation and use of the FLASH security options.Key Points•FLASH memory can be protected from access across the JTAG interface by setting bits in the FLASH Security Bytes to ‘0’.•FLASH memory can also be protected from read accesses by software by setting a Software Read Access Limit. (Used to allow the end-user to access some portions of FLASH memory.)•FLASH memory protected from software access should also be protected from JTAG access using the FLASH Security Bytes.•When protecting FLASH, the FLASH page containing the FLASH Security Bytes should also be protected. (FLASH cannot be unlocked using software).•If the end-user does not need access to FLASH memory, the entire FLASH memory can be protected by simply locking the entire FLASH memory from JTAG access (Software Read Limit is not needed in this case as the end-user cannot download software to access proprietary information).AN1202Rev. 1.1Preventing FLASH Access Via the JTAG Interface.One of the two ways to read, write, and erase the FLASH memory is via the JTAG interface (see application note “AN005 - Programming FLASH Through the JTAG Interface”.) The FLASH Pro-gram Memory Security Bytes located in the FLASH memory are used to prevent both read and/or write/ erase operations of any or all of the 512-byte mem-ory blocks via the JTAG interface.The FLASH security bytes are located in the FLASH memory as shown in Figure1 and Figure2 below. To protect a FLASH memory block from unauthorized read or write/erase operations across the JTAG interface, refer to the memory block chart (also located in each device’s data sheet). Attempting a read operation on a byte in a read-locked sector will return a value of ‘0’ and will set the FAIL bit in the FLASHDAT register to ‘1’, indicating a FLASH operation failure. (Please seeFigure 1. FLASH Security Bytes The C8051F0xx Family of Devices Figure 2. FLASH Security Bytes For The C8051F2xx Family of DevicesAN120application note, “AN005 - Programming FLASH Through the JTAG Interface” for more information about how to read FLASH data via the JTAG inter-face). Clearing a bit to logic ‘0’ in the Read Lock Byte will prevent the corresponding block of FLASH memory from being read via the JTAG interface.Attempting a write or erase operation on a byte in a write/erase-locked sector will be ignored and will set the FAIL bit in the FLASHDAT register to ‘1’indicating a FLASH operation failure. Clearing a bit to logic 0 in the write/erase lock byte will pre-vent the corresponding block of FLASH memory from write/erase operations via the JTAG interface.Clearing an entire security byte to 0x00 will protect the entire FLASH code space from that respective operation across the JTAG interface.NOTE: The FLASH Security bytes prevent access via JTAG only -- software can still access JTAG locked blocks! To prevent unauthorized access, the application should lock the entire FLASH memory. Locking all memory bytes will prevent an end-user from downloading code to unlocked memory space and using software to access information in the locked space. If an appli-cation must leave some memory unlocked, but the designer still wants to prevent access to some FLASH memory, the FLASH Access Limit feature should be used in conjunction with the security bytes. In an application that locks some blocks of FLASH memory yet leaves some blocks unlocked for the end-user, the block containing security bytes should always be write/erase locked to prevent unlocking the protected FLASH by erasing the FLASH page containing the security bytes.Device ErasePerforming a JTAG erase operation using the address of either the read lock byte or erase/write lock byte will automatically initiate erasure of the entire FLASH program space (with the exception of the RESERVED area.) This can only be per-formed via the JTAG interface, and not by soft-ware . If software attempts to erase any byte in the FLASH page containing the lock bytes, the erase operation is ignored. If a non-security byte in the memory block that contains the FLASH security bytes is addressed to perform a FLASH erase, only that 512-byte page will be erased (including the security bytes.)Preventing FLASH Access Via SoftwareNote: The Software Access Read Limit security option discussed in the following section is not available on the C8051F000/01/02 and C8051F010/11/12. In these devices, the entire FLASH user space should be read and write/erase locked using FLASH security bytes to protect intel-lectual property.Silicon Labs devices’ FLASH memory may be accessed via application software (see application note, “AN009 - Writing to FLASH from Applica-tion Code.”) This facilitates maximum flexibility in application design including the implementation of bootloading software, but does give a way for the end-user to access FLASH memory that has been locked from JTAG access (unless ALL of the FLASH memory is locked.) For this reason, Silicon Labs devices feature a FLASH access Software Read Limit to restrict access via downloaded appli-cation code. Used in conjunction with the security bytes to prevent JTAG access, the software read limit allows the application to prevent software access to some FLASH memory, while leaving some FLASH accessible to the end-user.The FLASH software access limit works as fol-lows. The designer defines an address as an access limit. FLASH memory from address 0x0000 up to and including the address defined as the software read limit is protected from software access. If code loaded into the FLASH above the software access limit address attempts to execute a MOVC instruction with a source address in the software read protected address space, a data value of 0x00AN1204Rev. 1.1will be returned. Code loaded into FLASH in the software protected space (below the FLACL boundary) is not restricted from executing. FLASH memory above the software access limit address boundary may be used as normal (i.e., read and write/erase operations may be performed by soft-ware), but may not write or erase code below the FLACL boundary. Thus, the application can protect code from unauthorized access, yet still leave FLASH memory usable to the end-user.NOTE: Software read protected FLASH should also be locked using the security bytes to prevent JTAG access to the protected memory blocks. (When locking only certain memory blocks, the memory block containing the security bytes should always be locked from JTAG access as well to pre-vent the end-user from unlocking FLASH mem-ory.)Setting the Software Read Limit The software read limit is set using the FLASH Access Limit special function register (FLACL). The upper byte of the desired software access limit address (the highest address the designer wishes to have software access protection) is moved into the FLACL register. The lower byte of the address will be 0x00. (See Figure3 below.) Thus, if the FLACL register is assigned the value 0x40, then the software access limit address will be 0x4000. Thus, all code in memory from 0x0000 to 0x4000 (including 0x4000) will not be accessible via software executing above this address. Code executing above the FLACL boundary may per-form jump and call instructions into protected memory space below the FLACL boundary. Only MOVX and MOVC operations are prevented by the Software Read Limit. To prevent access, the FLASH Security Bytes should also be used to pre-vent JTAG access of the memory blocks at and below 0x4000 for total protection (see the previous section, “Preventing FLASH Access Via the JTAG Interface.)If the application does not require FLASH memory to be programmable for the end-user, then it is best to lock the entire FLASH memory using the secu-rity bytes, and the software access read limit is not needed (the end-user will not be able to download code to FLASH to access protected information.) FLASH Write and Erase Enable BitsOne function of FLASH security is to prevent inad-vertent modification of code. Silicon Labs FLASH write and erase operations cannot occur via soft-ware unless they are enabled using the Program Store Write Enable (PSWE) and Program Store Erase Enable (PSEE) bits. In order to write to the FLASH memory, the PSWE bit must be set to 1. When the PSWE bit is set to ‘1’, the MOVX instruction writes to FLASH memory instead of XRAM (the default target). In order to erase a page of FLASH memory, the PSEE and PSWE bits must be set to ‘1’. When the PSEE bit is set to ‘1’, theAN120 FLASH control logic interprets a FLASH writeoperation as an erase operation. The PSEE andPSWE bits aid in preventing inadvertent write anderase modifications when they are not intended. Ofcourse, this does not perform the function of pro-tecting intellectual property access by an unautho-rized end-user, as the PSWE and PSEE bits arealways accessible. Always use the software readaccess limit and/or FLASH security bytes for pro-tection of intellectual property.Silicon Laboratories Inc.400 West Cesar Chavez Austin, TX 78701USASimplicity StudioOne-click access to MCU and wireless tools, documentation, software, source code libraries & more.

二、在KEIL下使用USB Debug Adapter
目前，开发C8051F主要使用的IDE是Keil，这里仅仅介绍在Keil下如何对它进行开发。
第一步：安装KeilC51，安装后请进行破解，破解工具在资料中已经给出。
第二步：安装“C8051的KEIL插件”，若KEIL版本为UV2，则选择安装“SiC8051F_uv2.exe”，若KEIL版本为UV3，则选择安装“SiC8051F_uv3.exe”，新版的“SiC8051F_uVision”支持KEIL UV4。
在安装时请注意，安装路径请一定要指向Keil安装目录。
第三步：安装“UtilDLL”，在安装时，也最好指向Keil安装目录。
第四步：设置Keil
首先请确保Keil已经被破解，然后打开Keil的Option，选中Debug页面，选择silicon...(请注意，只有正确安装了Keil 以及相关驱动，才能看见这个选项)。
选择SIlabs的调试工具，点击Settings，将出现如下界面。
请选择USB Debug Adapter，点击OK，（请注意，只有正确安装了U-EC6驱动，并将U-EC6插上电脑，才能选择该选项）。
完成这步后，可以点击使用KeiL进行调试了。
补充：使用Keil也可以进行Hex下载，并不调试。
进入Keil的Option菜单。
选择Utilities，选择Silicon….即可。
完成后可点击Keil面板上的按钮进行程序下载。
首次使用Keil、使用其他工具后再使用Keil进行调试或下载，Keil可能会提示固件更新。
这是正常现象，请点击确定进行升级，升级后即可正常使用。
三、使用批量下载工具
3.1 U-EC5中文下载程序
U-EC6 中文下载程序是silabs深圳代理商新华龙电子有限公司开发的一款用于C8051F 单片机的编程软件，可配合U-EC6使用，对C8051f单片机进行擦除，编程，加密，读取等操作。
该软件操作界面如下。
在“设置”－“通信口设置”里面选择USB仿真器，根据目标器件选择C2或JTAG接口类型，如下图。
使用U-EC6中文下载程序烧录C8051F单片机，烧录速度大于silabs官方软件，但是其稳定性较差，可能下载失败，并且可能导致U-EC6固件破坏，不推荐使用。
3.2 Silicon Laboratories Flash Utility
SiliconLab官方发布了一个专用于C8051F的下载软件FlashUtil，其速度比U-EC6中文下载程序稍慢，但是稳定性却高的多，软件界面如下所示。
设置好后点击Connect按钮，下面出现芯片型号则目标器件已识别。
3.3 Silicon Labs MCU Production Programmer
Silicon Labs MCU Production Programmer 也是SiliconLab官方发布了一个专用于C8051F的下载软件，软件界面如下所示。
四、EC6固件更新
本工作室U-EC6产品支持固件更新，以适应不断升级的芯片厂商软件，达到最好的使用性能。
固件更新分为手动更新和自动更新两种方式。
自动更新：当U-EC6正常工作时，若使用不同版本的PC软件或驱动，会提示固件更新，请点击“确定”，更新完成后可正常使用。
当EC6 在某些异常情况下，固件可能被破坏，如使用有问题的PC软件版本。
此时，可执行手动更新，打开Usb Reset软件，界面如下。
