Pinout

Pin Name Type Function
1 PD3 bidirectional Port D bit 3 is a bi-directional I/O pin with internal pull-up; it alternates as INT1 (external interrupt 1), OC2B (Timer/Counter2 compare match B output, which requires DDD3 set to output) and PCINT19.
2 PD4 bidirectional Port D bit 4 is a bi-directional I/O pin with internal pull-up; it alternates as XCK (USART external clock), T0 (Timer/Counter0 external counter input) and PCINT20.
3 GND power_in Ground.

5 GND power_in Ground.
6 VCC power_in Digital supply voltage.
7 PB6 bidirectional Port B bit 6 is used as XTAL1 (chip clock oscillator pin 1 or external clock input), TOSC1 or PCINT6 depending on fuse and ASSR settings; when used as a clock pin it cannot be used as an I/O pin.
8 PB7 bidirectional Port B bit 7 is used as XTAL2 (chip clock oscillator pin 2), TOSC2 or PCINT7 depending on fuse and ASSR settings; when used as a clock pin it cannot be used as an I/O pin.

10 PD6 bidirectional Port D bit 6 is a bi-directional I/O pin; as AIN0 (analog comparator positive input) it should be configured as input with the internal pull-up switched off, and it also alternates as OC0A and PCINT22.
11 PD7 bidirectional Port D bit 7 is a bi-directional I/O pin; as AIN1 (analog comparator negative input) it should be configured as input with the internal pull-up switched off, and it also serves as PCINT23.
12 PB0 bidirectional Port B bit 0 is a bi-directional I/O pin; it alternates as ICP1 (Timer/Counter1 input capture input), CLKO (divided system clock output) and PCINT0.
13 PB1 bidirectional Port B bit 1 is a bi-directional I/O pin; it alternates as OC1A (Timer/Counter1 compare match A output, requires DDB1 set to output) and PCINT1.
14 PB2 bidirectional Port B bit 2 is a bi-directional I/O pin; it alternates as SS (SPI slave select input), OC1B (Timer/Counter1 compare match B output, requires DDB2 set to output) and PCINT2.
15 PB3 bidirectional Port B bit 3 is a bi-directional I/O pin; it alternates as MOSI (SPI master output/slave input), OC2A (Timer/Counter2 compare match A output, requires DDB3 set to output) and PCINT3.
16 PB4 bidirectional Port B bit 4 is a bi-directional I/O pin; it alternates as MISO (SPI master input/slave output) and PCINT4.

18 AVCC power_in Supply voltage pin for the A/D converter, PC3:0 and ADC7:6; it should be externally connected to VCC even if the ADC is not used, and through a low-pass filter if the ADC is used.
19 ADC6 input Analog input to the A/D converter (TQFP and QFN/MLF package only), powered from the analog supply and serving as a 10-bit ADC channel.
20 AREF input Analog reference pin for the A/D converter.
21 GND power_in Ground.
22 ADC7 input Analog input to the A/D converter (TQFP and QFN/MLF package only), powered from the analog supply and serving as a 10-bit ADC channel.
23 PC0 bidirectional Port C bit 0 is a bi-directional I/O pin with internal pull-up; it can also be used as ADC input channel 0 (uses analog power) and PCINT8.
24 PC1 bidirectional Port C bit 1 is a bi-directional I/O pin with internal pull-up; it can also be used as ADC input channel 1 (uses analog power) and PCINT9.
25 PC2 bidirectional Port C bit 2 is a bi-directional I/O pin with internal pull-up; it can also be used as ADC input channel 2 (uses analog power) and PCINT10.
26 PC3 bidirectional Port C bit 3 is a bi-directional I/O pin with internal pull-up; it can also be used as ADC input channel 3 (uses analog power) and PCINT11.
27 PC4 bidirectional Port C bit 4 is a bi-directional I/O pin with internal pull-up; it alternates as SDA (2-wire serial data I/O, open-drain with spike filter when TWEN is set), ADC4 (uses digital power) and PCINT12.
28 PC5 bidirectional Port C bit 5 is a bi-directional I/O pin with internal pull-up; it alternates as SCL (2-wire serial clock I/O, open-drain with spike filter when TWEN is set), ADC5 (uses digital power) and PCINT13.
29 PC6 input Reset input when the RSTDISBL fuse is unprogrammed: a low level longer than the minimum pulse length (Table 29-3) generates a reset, and shorter pulses are not ensured to reset; if RSTDISBL is programmed it is an I/O pin with electrical characteristics differing from other Port C pins, and it also serves as PCINT14.
30 PD0 bidirectional Port D bit 0 is a bi-directional I/O pin with internal pull-up; it alternates as RXD (USART receive data input when the receiver is enabled) and PCINT16.
31 PD1 bidirectional Port D bit 1 is a bi-directional I/O pin with internal pull-up; it alternates as TXD (USART transmit data output, enabled when the transmitter is enabled) and PCINT17.
32 PD2 bidirectional Port D bit 2 is a bi-directional I/O pin with internal pull-up; it alternates as INT0 (external interrupt 0 input) and PCINT18.
