ATXMEGA192A3-MH

MCU 8Bit/16Bit XMEGA AVR RISC 192KB Flash 1.8V/2.5V/3.3V 64Pin QFN EP

Overview

The Atmel® AVR®XMEGA™ A3 is a family of low power, high performance and peripheral rich CMOS 8/16-bit microcontrollers based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the XMEGA A3 achieves throughputs approaching 1 Million Instructions Per Second MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
