W77E516解密

　　WINBOND芯片解密是世纪芯芯片解密研究所在单片机解密、IC芯片解密技术研究中涉及的一类典型芯片， WINBOND（华邦）系列单片机解密一般来说有老版本和新版本之分，老本版的芯片解密难度较小，解密成功率和可靠性都较强，因此，芯片解密的周期短、价格低，而新版本芯片由于改进了加密机制，解密难度较大，解密费 用较高。
　　针对此类情况，在成功破解大部分老版本WINBOND系列芯片的基础上，目前，世纪芯芯片解密研究所投入更多 的精力进行新版本芯片的破解，且已经取得了一系列技术研究成果。而针对部分新版本的高难度疑难型解密芯片 ，客户如果有解密需求，我们也能够为其提供解密方案的开发，只是在解密周期较长，解密费用及开发费用相对 较高，请客户事先考虑相关项目详情。
　　下面我们将针对W77E516芯片的主要技术特征做简单介绍，供大家参考借鉴，有W77E516芯片解密以及其他各 类WINBOND系列单片机解密需求者欢迎与我们联系咨询更多详情
　　The W77E516 is a fast 8051 compatible microcontroller with a redesigned processor core without wasted clock and memory cycles. As a result, it executes every 8051 instruction faster than the original 8051 for the same crystal speed. Typically, the instruction executing time of W77E516 is 1.5 to 3 times faster then that of traditional 8051, depending on the type of instruction. In general, the overall performance is about 2.5 times better than the original for the same crystal speed. Giving the same throughput with lower clock speed, power consumption has been improved. Consequently, the W77E516 is a fully static CMOS design; it can also be operated at a lower crystal clock. The W77E516 contains In-System Programmable (ISP) 64 KB Flash EPROM; 4KB auxiliary Flash EPROM for loader program; operating voltage from 4.5V to 5.5V; on-chip 1 KB MOVX SRAM; three power saving modes.
