  在芯片解密过程中,对单片机本身的内部结构和加密性质进行了解是客户及解密工程师的必修课,对于解密工程师来说,只有深入了解芯片本身的加解密特征和加密算法,才能选择最合适的解密方案,极大保证解密的可靠性和成功率。而对于客户来说,对芯片加解密特征进行了解,能够帮助其在解密项目合作中进行技术实现理解,对解密项目进行沟通和监控,对解密难易程度以及解密费用等方面进行参考评估。我们提供对SST65P542R单片机的基本介绍,供客户及解密工程师参考借鉴。
  关于SST65P542R
  The SST65P542R is a member of SST’s 8-bit application specific microcontroller family targeted for IR remote controller applications.
  The SST65P542R microcontroller provides high functionality to infrared remote controller products. The device offers flexibility to store different remote control configurations for controlling multiple appliances. The configurations are either programmed at the factory during the manufacturing process or downloaded through firmware.
  Using SST’s SuperFlash nonvolatile memory technology,the SST65P542R enhances the functionality and reduces the cost of conventional universal remote controller devices by integrating multiple functions of a remote controller system in a single chip solution. The built-in LED I/O ports can directly drive LED indicators. The IR transmitter port drives signals to the infrared transmitter, which, in turn, remotely controls the appliances.
