AVR32DD14-I from Microchip Tech, in a SOIC-14-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference for the device. |
| 2 | PF6 | input | Input-only pin PF6, which serves as the active-low external RESET input when enabled by the RSTPINCFG fuse bit. |
| 3 | PF7 | bidirectional | PF7 is the UPDI programming/debug pin, configured as UPDI with pull-up by default (UPDIPINCFG fuse), with alternate SS and EVOUTF functions. |
| 4 | PA0 | bidirectional | PA0 is a general-purpose I/O pin that also serves as XTAL32K1/XTALHF1 crystal input and EXTCLK external clock input, with TxD, MOSI, SDA, WO0 and LUT0-IN0 alternate functions. |
| 5 | PA1 | bidirectional | PA1 is a general-purpose I/O pin that also serves as XTAL32K2/XTALHF2 crystal pin, with RxD, MISO, SCL, WO1 and LUT0-IN1 alternate functions. |
| 6 | PC1 | bidirectional | PC1 is a general-purpose I/O pin on the VDDIO2 (MVIO) domain with ADC input AIN29 (when MVIO is disabled) and USART1 RxD, WO1 and LUT1-IN1 functions. |
| 7 | PC2 | bidirectional | PC2 is a general-purpose I/O pin on the VDDIO2 (MVIO) domain with TWI client SDA (Fm+), ADC input AIN30, AC input AINN3, ZCD input ZCIN, USART1 XCK, EVOUTC and LUT1-IN2 functions. |
| 8 | PC3 | bidirectional | PC3 is a general-purpose I/O pin on the VDDIO2 (MVIO) domain with TWI client SCL (Fm+), ADC input AIN31, AC input AINP4, USART1 XDIR and LUT1-OUT functions. |
| 9 | VDDIO2 | power_in | Supply for the multi-voltage I/O pins on PORTC; connect to VDD in single-supply mode or to a separate I/O voltage in dual-supply mode. |
| 10 | PD4 | bidirectional | PD4 is a general-purpose I/O pin on the VDD domain with ADC input AIN4 and alternate TxD, MOSI, WO4 and TCD0 WOC functions. |
| 11 | PD5 | bidirectional | PD5 is a general-purpose I/O pin on the VDD domain with ADC input AIN5 and alternate RxD, MISO, WO5 and TCD0 WOD functions. |
| 12 | PD6 | bidirectional | PD6 is a general-purpose I/O pin on the VDD domain with ADC input AIN6, AC input AINP3, DAC output VOUT, and alternate XCK, TxD, SCK and LUT2-OUT functions. |
| 13 | PD7 | bidirectional | PD7 is a general-purpose I/O pin on the VDD domain with external reference input VREFA, ADC input AIN7, AC input AINN2, and alternate XDIR, RxD, SS and EVOUTD functions. |
| 14 | VDD | power_in | Positive supply voltage for the device and its non-MVIO I/O pins. |
