 ATmega32 is a low power CMOS 8-bit high performance microcontroller from Atmel’s Mega AVR family. It is based on enhanced RISC (Reduced Instruction Set Computing) architecture with 131 powerful instructions. Most of the instructions it can execute in one machine cycle, achieving throughputs approaching 1 MIPS per MHz, thus enabling system designers to optimize power consumption versus processing speed. Atmega16A can work on the maximum frequency of 16MHz. It has 32 KB programmable flash memory, static RAM of 2 KB and EEPROM of 1 KB. It is quite similar to Atmega16 microcontroller.
