Pinout

Pin Name Type Function
1 VCC power_in Digital supply voltage, specified over 1.8 to 5.5V in the features list.
2 PA0 bidirectional Bi-directional I/O port pin with individually selectable internal pull-up, multiplexed with ADC0/AIN0 analog inputs, T0, CLKI external clock, PCINT0 and the TPICLK serial programming clock.
3 PA1 bidirectional Bi-directional I/O port pin with individually selectable internal pull-up, multiplexed with ADC1/AIN1 analog inputs, OC0B output, PCINT1 and the TPIDATA serial programming data.
4 PA2 input Reset input where a low level longer than the minimum pulse length generates a reset, and the pin can also be used as a (weak) I/O pin.
5 PB1 bidirectional Bi-directional I/O port pin with internal pull-up, multiplexed with ADC5, CLKO system clock output, INT0 external interrupt, XCK0, OC0A output and PCINT9.
6 PB2 bidirectional Bi-directional I/O port pin with internal pull-up, multiplexed with ADC6, ICP0 input capture, TxD0 USART output and PCINT10.
7 PB3 bidirectional Bi-directional I/O port pin with internal pull-up, multiplexed with ADC7, ACO analog comparator output, RxD0 USART input, T0 and PCINT11.
