AVR核将32个工作寄存器和丰富的指令集联结在一起。所有的工作寄存器都与算术逻辑单元ALU直接相连，允许在一个时钟周期内执行的单条指令同时访问2个独立的寄存器。这种结构提高了代码效率，使AVR得到了比普通CISC单片机高将近10倍的性能。 ATtiny12 工作于空闲模式时，CPU将停止运行，而定时器/计数器和中断系统将继续工作；掉电模式时振荡器停止工作，所有功能都被禁止，而寄存器内容得到保留。只有外部中断或硬件复位才可以退出此状态。引脚电平变化中断的特点使得ATtiny12 对外部事件有很高的响应性，同时具有掉电模式的低功耗优点。 ATtiny12 内部集成有RC振荡器，其固定频率为1MHz。它还可以通过XTAL1和XTAL2引脚外接晶体振荡器或陶瓷振荡器。当使用外部时钟时，XTAL2应悬空。通过熔丝位控制，可以有多种时钟选择。 The ATtiny12 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny10/11/12 achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general-purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
