Microchip Technology AVR® XMEGA® 8/16-bit Microcontrollers

Microchip AVR XMEGA 8/16-bit Microcontrollers are low-power, high-performance and peripheral-rich CMOS 8/16-bit microcontrollers based on the AVR enhanced RISC architecture. By executing instructions in a single clock cycle, the Microchip AVR XMEGA 8/16-bit Microcontrollers achieve throughputs CPU approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed. AVR XMEGA 8/16-bit Microcontrollers combine a rich instruction set with 32 registers that are directly connected to the arithmetic logic unit (ALU), allowing two independent registers to be accessed in a single instruction, executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs many times faster than conventional single-accumulator or CISC based microcontrollers.
