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[edit]
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[edit]
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[edit]
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.
