STC单片机是以51内核为主的系列单片机,它是由笙泉科技设计,国内宏晶科技公司贴牌生产的,这个芯片设计的时候就吸取其它51系列单片很容易被解密的教训,改进了加密机制.STC单片机出厂的时候就已经完全加密,且部份加入了ID号,用户程序是ISP/IAP机制写入,编程的时候是一边校验一边写,无法读出命令,这个增加了解密难度,STC厂家号称STC所有系列无法解密,是的,新一代的宏晶相对于老的宏晶,解密难度大增加了,老一代的宏晶直接解密器一读就可以进行芯片解密,一般是不用破坏母片的,而新一代的STC,并非解密器就能解密,我司现在面对广大客户提供新一代宏晶芯片解密,欢迎大家前来咨询
STC12LE5A60AD系列单片机为3V器件,如果用户在引脚加上5V电压,将会有电流从引脚流向VDD,这样导致额外的功率消耗。因此,建议不要在准双向口模式中向3V单片机引脚施加5V电压,如使用的话,要加限流电阻,或用二极管做输入隔离,或用三极管做输出隔离。
准双向口带有一个施密特触发输入以及一个干扰抑制电路。
准双向口读外部状态前,要先锁存为 ‘1’,才可读到外部正确的状态。
下面是关于STC12LE5A60AD芯片内部存储的相关介绍
Program memory is the memory which stores the program codes for the CPU to execute. There is 8/16/20/32/40/48/52/56/62K-bytes of flash memory embedded for program and data storage. The design allows users to configureit as like there are three individual partition banks inside. They are called AP(application program) region, IAP(In-Application-Program) region and ISP (In-System-Program) boot region. AP region is the space that userprogram is resided. IAP(In-Application-Program) region is the nonvolatile data storage space that may be usedto save important parameters by AP program. In other words, the IAP capability of STC12C5A60S2 providesthe user to read/write the user-defined on-chip data flash region to save the needing in use of external EEPROMdevice. ISP boot region is the space that allows a specific program we calls !°ISP program!± is resided. Inside thISP region, the user can also enable read/write access to a small memory space to store parameters for specificpurposes. Generally, the purpose of ISP program is to fulfill AP program upgrade without the need to remove thedevice from system. STC12C5A60S2 hardware catches the configuration information since power-up durationand performs out-of-space hardware-protection depending on pre-determined criteria. The criteria is AP regioncan be accessed by ISP program only, IAP region can be accessed by ISP program and AP program, and ISPregion is prohibited access from AP program and ISP program itself. But if the !°ISP data flash is enabled!±, ISprogram can read/write this space. When wrong settings on ISP-IAP SFRs are done, The !°out-of-space!± happenand STC12C5A60S2 follows the criteria above, ignore the trigger command.
宏晶STC的10、11、新版12系列单片机由于采用宏晶第六代加密技术,在低版本STC89、stc90等系列单片机基础上增强了加密性能,推出之初被认为是无法破解的单片机。而橙盒科技解密工程师开发的独家解密方案,可一次性100%破解成功,且针对部分存在软加密的程序,我们也能够为客户进行程序修改,以确保功能100%正确。
橙盒科技目前通过逐步业务调整,正投入全部技术研究力量集中精力进行各类高难度及疑难型IC芯片解密方案的开发及现有解密方案的完善,致力于进一步降低各类疑难型IC解密成本,缩短解密周期,为客户带来更多实实在在的利益。
