MICROCHIP ATXMEGA64A4U-AN

The AVR XMEGA is a family of low power, high performance, and peripheral rich 8/16 -bit microcontrollers based on the AVR enhanced RISC architecture. By executing instructions in a single clock cycle, the AVR XMEGA devices achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed.
