Overview
ATtiny24A/44A/84A are low-power CMOS 8-bit microcontrollers based on the AVR enhanced
RISC architecture. By executing powerful in structions in a single clock cycle, the
ATtiny24A/44A/84A 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 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.
