AT90CAN64单片机也是深圳芯片解密研究所目前已经成功突破的AVR单片机解密系列之一，AVR单片机内嵌高质量的Flash程序存储器，擦写方便，支持ISP和IAP，便于产品的调试、开发、生产、更新。内嵌长寿命的EEProm可长期保存关键数据，避免断电丢失。片内大容量的RAM不仅能满足一般场合的使用，同时也更有效的支持使用高级语言开发系统程序,并可像MCS-51单片机那样扩展外部 RAM。
AVR单片机的I/O线全部带可设置的上拉电阻、可单独设定为输入/输出、可设定（初始）高阻输入、驱动能力强（可省去功率驱动器件）等特性，使的得I/O口资源灵活、功能强大、可充分利用。
AT90CAN64 是一种基于AVR增强型RISC结构的低功耗CMOS 8-位单片机。通过执行以一个单时钟周期的高效指令，AT90CAN64每MHz能达1MIPS，这就可让系统设计人员将功率损耗与处理速度优化。AVR内核具有丰富的指令集并带有32个通用目的工作寄存器。32个寄存器全都直接连到运算逻辑单元(ALU)，允许两个独立的寄存器以在一个时钟周期执行单个指令的方式访问。其结果就是，采用这种结构在速度比常规的RISC单片机快10倍的同时代码效率更高。
AT90CAN64 是采用Atmel高密度非易失存储器技术制造的，其在片ISP Flash允许程序存储器通过一个常规的非易失存储器编程器或一个运行在AVR核上的在片引导程序，经一个SPI串口在系统重新编程。引导程序能够采用任何接口将应用程序下载到Flash存储器中。在应用Flash区更新时，在引导Flash区中的软件将继续运行，提供真正的读-写操作。通过将8-位RISC CPU与在系统自编程Flash融合在一个单芯片上，AT90CAN64便成为一个高效的单片机，可以为很多嵌入式控制应用提供一种极为灵活且成本有效的解决方案。
