ATmega48PA/88PA/168PA
AVRВ® Microcontroller with picoPowerВ® Technology
Introduction
В® The picoPower ATmega48PA/88PA/168PA is a low-power CMOS 8-bit microcontroller based on the
В®
AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the
В®
ATmega48PA/88PA/168PA achieves throughputs close to 1 MIPS per MHz. This empowers system
designers to optimize the device for power consumption versus processing speed. Feature
