Overview
The Atmel ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P is a low-power CMOS
8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful

cycle,
the
ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P achieves throughputs approach-
ing 1 MIPS per MHz allowing the system designer to optimize power consumption versus
processing speed.

Block diagram.
The AVR core combines a rich instruction set with 32 general purpose working registers. All the
32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent
registers to be accessed in one single instruction executed in one clock cycle. The resulting
architecture is more code efficient while achieving throughputs up to ten times faster than
conventional CISC microcontrollers.
