ATtiny24, ATtiny44, and ATtiny84 are microcontrollers in the Atmel AVR family. All are available in either the 14-pin DIP 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.
ATtiny24
The ATtiny24 has 2 KB of flash, 128 B of SRAM, 128 B of EEPROM, and includes the following features:
- 2 timers
- 4 touch channels
- 1 SPI
- 1 I2C
- 10-bit ADC with 8 channels
- 1 analog comparator
- temperature sensor
- 4 PWM channels
- watchdog
ATtiny24A
The ATtiny24A is the picoPower version of the ATtiny24.
ATtiny44
The ATtiny44 is identical to the ATtiny24 except that it has 4 KB of flash, 256 B of SRAM, 256 B of EEPROM, and includes 6 touch channels.
ATtiny44A
The ATtiny44A is the picoPower version of the ATtiny44.
ATtiny84
The ATtiny84 is identical to the ATtiny24 except that it has 8 KB of flash, 512 B of SRAM, and 256 B of EEPROM.
ATtiny84A
The ATtiny84A is the picoPower version of the ATtiny84.
