The Microchip ATmega324PA 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 ATmega324PA achieves throughputs approaching 1 MIPS per MH–allowing the system designer to optimize power consumption versus processing speed.
