Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Supply pin; the device operates from 1.8 V to 5.5 V, with operation guaranteed down to 1.8 V or VBOD (BODLEVEL=1.8 V), whichever is lower. |
| 2 | PA4 | bidirectional | General purpose I/O pin PA4 that also carries ADC0 analog input AIN4 and PTC line X0/Y0 per the multiplexing table. |
| 3 | PA5 | bidirectional | General purpose I/O pin PA5 that also carries ADC0 analog input AIN5 and PTC line X1/Y1 per the multiplexing table. |
| 4 | PA6 | bidirectional | General purpose I/O pin PA6 that also carries ADC0 analog input AIN6, PTC line X2/Y2, the DAC analog output OUT, and the AC0 negative input AINN0. |
| 5 | PA7 | bidirectional | General purpose I/O pin PA7 that also carries ADC0 analog input AIN7, PTC line X3/Y3, and the AC0 positive input AINP0. |
| 6 | PB3 | bidirectional | General purpose I/O pin PB3 that is also the 32.768 kHz crystal oscillator connection TOSC1 per Table 5-1. |
| 7 | PB2 | bidirectional | General purpose I/O pin PB2 that is also the 32.768 kHz crystal oscillator connection TOSC2 and an event output EVOUT1 per Table 5-1. |
| 8 | PB1 | bidirectional | General purpose I/O pin PB1 that also carries ADC0 analog input AIN10 and PTC line X4/Y4 per the multiplexing table. |
| 9 | PB0 | bidirectional | General purpose I/O pin PB0 that also carries ADC0 analog input AIN11 and PTC line X5/Y5 per the multiplexing table. |
| 10 | PA0/RESET/UPDI | bidirectional | Multiplexed pin that is GPIO PA0, the RESET input, or the UPDI programming/debug interface, selected by the RSTPINCFG fuse; it also carries ADC0 input AIN0. |
| 11 | PA1 | bidirectional | General purpose I/O pin PA1 that also carries the BREAK function, ADC0 analog input AIN1, and USART0 TXD. |
| 12 | PA2 | bidirectional | General purpose I/O pin PA2 that also carries event output EVOUT0, ADC0 analog input AIN2, and USART0 RxD. |
| 13 | PA3 | bidirectional | General purpose I/O pin PA3 that also carries external clock input EXTCLK and ADC0 analog input AIN3. |
| 14 | GND | power_in | Ground reference for the device. |
