MICROCHIP (US Microchip)/ATMEGA32A-AU TQFP-44 8-bit Microcontroller AVR 32K Flash -56806

The Atmel?AVR? ATmega32A 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 ATmega32A achieves throughputs
approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing
speed.
