It is available in the 20-pin SOIC, 20-pin TSSOP, or 20-pin VQFN package with a 4, 8, or 12 MHz selected clock speed. Running higher clock speeds require higher minimum operating voltages, with 1.8 volts for 4 MHz, 2.7 volts for 8 MHz, and 4.5 volts for 12 MHz. It has the following features:<br /> <br /> * 1 SPI<br /> * 1 I2C<br /> * 10-bit ADC with 12 channels<br /> * 1 analog comparator<br /> * temperature sensor<br /> * 2 timers<br /> * 2 PWM<br /> * internal RC oscillator<br /> * watchdog<br /> <br /> [[Category:Components]]<br /> [[Category:AVR]]</div>
