2. Overview

The ATmega16U4/ATmega32U4 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

ATmega16U4/ATmega32U4 achieves throughputs approaching 1 MIPS per MHz allowing the

system designer to optimize power consumption versus processing speed.
