AT87C52X2 IC解密

芯片解密、IC解密、单片机解密技术通常以高时间分辨率来监控处理器在正常操作时所有电源和接口连接的模拟特性，并通过监控它的电磁辐射特性来实施攻击。因为单片机是一个活动的电子器件，当它执行不同的指令时，对应的电源功率消耗也相应变化。这样通过使用特殊的电子测量仪器和数学统计方法分析和检测这些变化，即可获取单片机中的特定关键信息。

单片机解密探针技术是直接暴露芯片内部连线，然后观察、操控、干扰单片机以达到攻击目的。

　　AT87C52X2 概述

　　TS80C52X2 is high performance CMOS ROM, OTP, EPROM and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller.

　　The TS80C52X2 retains all features of the 80C51 with extended ROM/EPROM capacity (8 Kbytes), 256 bytes of internal RAM, a 6-source, 4-level interrupt system, an on-chip oscilator and three timer/counters.

　　In addition, the TS80C52X2 has a dual data pointer, a more versatile serial channel that facilitates multiprocessor communication (EUART) and an X2 speed improvement mechanism.

　　The fully static design of the TS80C52X2 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data.

　　The TS80C52X2 has 2 software-selectable modes of reduced activity for further reduction in power consumption. In the idle mode the CPU is frozen while the timers, the serial port and the interrupt system are still operating. In the power-down mode the RAM is saved and all other functions are inoperative.
