The ATmega48A-AU is  a  low  power,  CMOS  8-bit  microcontrollers  based  on  the AVR® enhanced RISC architecture. By executing instructions in a single clock cycle, the devices achieve CPU through put approaching one million instructions per second (MIPS) per mega hertz, allowing the system designer to optimize power consumption versus processing speed.
