ATtiny4, ATtiny5, ATtiny9, and ATtiny10 are microcontrollers in the Atmel AVR family. All are available in either the 6-pin SOT23 or the 8-pin UDFN package with a 10 or 12 MHz clock speed.
The ATtiny4 has 512 B of flash, 32 B of SRAM and the following features:
- 1 timer
- 1 analog comparator
- 2 PWM channels
The ATtiny5 is identical to the ATtiny4 except that it includes an 8-bit ADC with 4 channels.
The ATtiny9 is identical to the ATtiny4 except that is has 1 KB of flash.
The ATtiny10 is identical to the ATtiny4 except that it has 1 KB of flash, includes 1 touch channel and an 8-bit ADC with 4 channels.
