8-bit AVR Microcontroller ATmega48/V / 88/V / 168/V DATASHEET COMPLETE Introduction The Atmel ATmega48/V/ 88/V /168/V is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega48/V/ 88/V /168/V achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.
