DS89C430芯片解密

DS89C430芯片解密是橙盒芯片解密研究所在DALLAS系列芯片解密技术研究中成功破解的典型芯片型号，目前，针对DS89C430芯片以及DS89系列其他典型的DALLAS芯片，橙盒芯片解密研究所均能够提供高效可靠、价格合理的解密方案。

　 The DS89C430 offer the highest performance available in 8051-compatible microcontrollers. They feature newly designed processor cores that execute instructions up to 12 times faster than the original 8051 at the same crystal speed. Typical applications will experience a speed improvement up to 10x. At 1 million instructions per second (MIPS) per megahertz, the microcontrollers achieve 33 MIPS performance from a maximum 33MHz clock rate.
