Introduction
The ATmega32A is a low power, CMOS 8-bit microcontrollers based on the AVR® enhanced RISC architecture.
The ATmega32A is a 40/44-pins device with 32 KB Flash, 2 KB SRAM and 1 KB EEPROM. By executing
instructions in a single clock cycle, the devices achieve CPU throughput approaching one million
instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption
versus processing speed.
