　　这里，我们提供对ST62E20CF1芯片的基本介绍及功能特征分析供客户及解密工程师参考借鉴。
　　ST62E20CF1芯片简介
　　The ST62E20C is the erasable EPROM version of the ST62T08C, T09C, T10C and T20C devices,which may be used during the development phase for the ST62T08C, T09C, T10C and T20C target devices, as well as the respective ST6208C, 09C,10C and 20C ROM devices.
　　OTP and EPROM devices are functionally identical.OTP devices offer all the advantages of user programmability at low cost, which make them the ideal choice in a wide range of applications where frequent code changes, multiple code versions or last minute programmability are required.
　　The ROM based versions offer the same functionality,selecting the options defined in the programmable option bytes of the OTP/EPROM versions in the ROM option list (See Section 11.6 on page 96).
