2. Overview
8127DS–AVR–02/10
ATtiny4/5/9/10 are low-power CMOS 8-bit microcontrollers based on the compact AVR
enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the
ATtiny4/5/9/10 achieve 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.
The resulting architecture is compact and code efficient while achieving throughputs up to ten
times faster than conventional CISC microcontrollers.
