The ATmega329P/3290P 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
ATmega329P/3290P achieves throughputs approaching 1MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.
The Atmel
All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two inde-
pendent registers to be accessed in one single instruction executed in one clock cycle. The
