AT90CAN32 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，AT90CAN32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。
AT90CAN32 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，AT90CAN32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。
AT90CAN32 AVR可由成套的程序和系统开发工具支持，包括：仿真调试器(JTAG ICE mkII + AVR Studio)、C编译器(GCC Win AVR或IAR EWA AVR)、开发板(DVK90CAN1)等。
