2. Overview
ATtiny828 is a low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. By executing
powerful instructions in a single clock cycle, the ATtiny828 achieves throughputs approaching 1 MIPS per MHz allowing
the system designer to optimize power consumption versus processing speed.

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 a 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.
