ATmega163(L) Description
The ATmega163 is a low-power CMOS 8-bit microcontroller based on the AVR architec- ture. By executing powerful instructions in a single clock cycle, the ATmega163 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
