          +The Atmel®  ATmega128A 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 ATmega128A achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.
