Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Supply voltage input; the Features section gives the operating range as 1.8 V to 5.5 V. |
| 2 | PB0 | bidirectional | Port B bit 0 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate functions are XTAL1/CLKI (PCINT8). |
| 3 | PB1 | bidirectional | Port B bit 1 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate function is XTAL2 (PCINT9). |
| 4 | PB3 | bidirectional | Port B bit 3 is a bidirectional I/O with a selectable internal pull-up that acts as the active-low RESET input (minimum pulse length per Table 20-4) unless the RSTDISBL fuse is programmed to 0, and can also be used as a weak I/O pin; alternate functions are PCINT11 and dW. |
| 5 | PB2 | bidirectional | Port B bit 2 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate functions are INT0/OC0A/CKOUT (PCINT10). |
| 6 | PA7 | bidirectional | Port A bit 7 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate functions are ADC7/ICP/OC0B (PCINT7). |
| 7 | PA6 | bidirectional | Port A bit 6 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate functions are ADC6/OC1A/SDA/MOSI/DI (PCINT6). |
| 8 | PA5 | bidirectional | Port A bit 5 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate functions are ADC5/DO/MISO/OC1B (PCINT5). |
| 9 | PA4 | bidirectional | Port A bit 4 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate functions are ADC4/USCK/SCL/T1 (PCINT4). |
| 10 | PA3 | bidirectional | Port A bit 3 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate functions are ADC3/T0 (PCINT3). |
| 11 | PA2 | bidirectional | Port A bit 2 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate functions are ADC2/AIN1 (PCINT2). |
| 12 | PA1 | bidirectional | Port A bit 1 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate functions are ADC1/AIN0 (PCINT1). |
| 13 | PA0 | bidirectional | Port A bit 0 is a bidirectional I/O with a selectable internal pull-up, tri-stated when reset is active; alternate functions are ADC0/AREF (PCINT0). |
| 14 | GND | power_in | Ground reference for the device. |
