ATmega164PA/324PA/644PA
2. Overview
The ATmega164PA/324PA/644PA 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
ATmega164PA/324PA/644PA achieves throughputs approaching 1 MIPS per MHz allowing the
system designer to optimize power consumption versus processing speed.

Figure 2-1. 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 con-
ventional CISC microcontrollers.
