ATMEGA3290PA-AU Devices Electronic

Product Overview

The ATMEGA3290PA-AU Devices Electronic is a low-power CMOS 8-bit microcontroller based on the Atmel®AVR® enhanced RISC architecture. By executing powerful instructions in a single clock

cycle, the ATMEGA3290PA-AU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
