1.1 Disclaimer

Typical values contained in this datasheet are based on simulations and characterization of

other AVR microcontrollers manufactured on the same process technology. Min and Max values

will be available after the device is characterized.

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.
