ATtiny85 Microcontroller


ATtiny85 is smallest microcontroller in ATMEL’s AVR family having less number of pins. It has 8 pins in total in which 6 pins are for programmable Input/Output. It was developed for low power applications such as (battery operated applications). 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.
