Product Description

ATMEGA16U2-AU IC MCU 8BIT 16KB FLASH 32TQFP Microchip Technology

Product Details

 

Overview

The ATmega8U2/16U2/32U2 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 ATmega8U2/16U2/32U2 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
