'''ATtiny25''', '''ATtiny45''', and '''ATtiny85''' are microcontrollers in the Atmel AVR family. All are available in either the 8-pin DIP, 8-pin SOIC, or the 20-pin QFN package with a 10 or 20 MHz clock speed. The higher clock speed version has a higher minimum operating voltage of 2.7 volts.

== ATtiny25 ==

The ATtiny25 has 2 KB of flash, 128 B of SRAM, 128 B of EEPROM and the following features:

* 4 touch channels
* 1 SPI
* 1 I2C
* 10-bit ADC with 4 channels
* 1 analog comparator
* temperature sensor
* 2 timers
* 6 PWM channels
* internal RC oscillator
* watchdog

== ATtiny45 ==

The ATtiny45 is identical to the ATtiny25 except that it has 4 KB of flash, 256 B of SRAM, 256 B of EEPROM, and 3 touch channels.

This device is also available in the 8-pin TSSOP package.

== ATtiny85 ==

The ATtiny85 is identical to the ATtiny25 except that is has 8 KB of flash, 512 B of SRAM, 512 B of EEPROM, and 3 touch channels.
