ATmega163(L)

Description

The ATmega163 is a low-power CMOS 8-bit microcontroller based on the AVR architecture. By executing powerful instruc-

tions 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.
