Block Diagram
The ATmega48A/48PA/88A/88PA/168A/168PA/328/328P is a low-power CMOS 8-bit microcon-
troller based on the AVR enhanced RISC architecture. By executing powerful instructions in a
single clock cycle, the ATmega48A/48PA/88A/88PA/168A/168PA/328/328P achieves through-
puts approaching 1 MIPS per MHz allowing the system designer to optimize power consumption
versus processing speed.
Figure 2-1.
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
