AT87C5103单片机解密

单片机解密有四种解密手法：软件攻击、电子探测攻击、过错产生技术、探针技术。芯片解密的侵入型攻击（物理攻击），这类攻击需要破坏封装，然后借助半导体测试设备、显微镜和微定位器，在专门的实验室花上几小时甚至几周时间才能完成。所有的微探针技术都属于侵入型攻击。另外三种方法属于非侵入型攻击，被攻击的单片机不会被物理损坏。

世纪芯科技长期从事单片机解密（MCU解密）、专用IC解密、芯片解密、PLD芯片解密、CPLD芯片解密、FPGA解密、DSP芯片解密、ARM芯片解密，软件解密，单片机软硬件开发等技术研究与技术服务。

　　AT87C5103 概述：

　　The AT8xC5103 is a high-performance ROM/OTP version of the 80C51 8-bit Microcontroller in 16 and 24-pin packages.

　　The AT8xC5103 contains a standard C51 CPU core with 12 Kbytes ROM/OTP program memory, 256 bytes of internal RAM, 256 bytes of extended internal RAM, a 5- sources 4-level interrupt system, two timer/counters and a SPI serial bus controller. The AT8xC5103 is also dedicated for analog interfacing applications. For this, it has a five channels Programmable Counter Array.

　　In addition, the AT8xC5103 implements the X2 speed improvement mechanism. The X2 feature allows to keep the same CPU power at a divided by two oscillator frequency.
