16K Byte self-programming Flash Program Memory, 1K Byte SRAM, 512 Bytes EEPROM, 8 Channel 10-bit A/D-converter(TQFP/MLF). debugWIRE On-chip Debug System. Up to 20 MIPS throughput at 20 MHz.
ATmega168 是基于AVR增强型RISC结构的低功耗8位CMOS微控制器。由于其先进的指令集以及单时钟周期指令执行时间,ATmega168 的数据吞吐率高达 1 MIPS/MHz,从而可以缓减系统在功耗和处理速度之间的矛盾。
ATmega168 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced
RISC architecture. By executing powerful instructions in a single clock cycle, theATmega168 achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power onsumption versus processing speed.
