SKU: IC-016 Manufacturer: Microchip Mfg Part Number: ATTINY85-20PU Category: Tags: , , ,


Have you ever wanted to build your very own tiny microcontroller on a breadboard? The Atmel’s ATTiny85 is probably perfect for the job! This Arduino compatible chip can run on anything between 2.7 and 5.5VDC so it is ideally suited for 3.3 and 5V circuits. The chip has 6 general purpose digital I/O pins; four of these pins can also be used as analog inputs while the two remaining pins can be used for PWM. An internal 8MHz oscillator means no external clock signal is required.

Please Note: An AVR programmer will be needed to program this chip.



  • 2.7 – 5.5 VDC
  • 6 I/O channels
  • 8K of program memory
  • 4 Channel 10 Bit ADC
  • Programmable in circuit
  • Arduino compatible
