ATtiny20
ATtiny20 is a low-power CMOS 8-bit microcontroller based on the compact AVR enhanced
RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny20
achieves throughputs 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 16 general purpose working registers and
system registers. All 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.
