ATtiny85 8-Bit tinyAVR Microcontrollers


The Atmel ATtiny85 Microcontroller is an 8-bit device based on the AVR enhanced RISC architecture. Being an Atmel tinyAVR device the ATtiny85 is packs performance and power efficiency into a small package, perfect for applications where space is at a premium. By executing powerful instructions in a single clock cycle the ATtiny85 achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and speed.
