Atmel 8-bit AVR Microcontroller with 2/4/8K Bytes In-System Programmable Flash

Atmel Corporation 

2. Overview

The ATtiny25/45/85 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By

executing powerful instructions in a single clock cycle, the ATtiny25/45/85 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 one

single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving

throughputs up to ten times faster than conventional CISC microcontrollers.
