From the manufacturer of the common ATmega328P found in many Arduinos, the 8-bit ATtiny85 is an eight pin microcontroller.
If you have a simple Arduino project and want to make it smaller in size then the ATtiny85 is a great way to do so.
You can use the Arduino IDE and another Arduino board to program this little guy.
