ATTINY1614-SSN from Microchip Tech, in a SOIC-14. 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	VDD	power_in	Supply pin for the device; the operating supply voltage range is 1.8V to 5.5V.
2	PA4	bidirectional	General-purpose I/O pin PA4 on the VDD power domain, multiplexed with ADC0 AIN4, AC0 AIN0, SPI0 SS and TCA0 WO4 functions.
3	PA5	bidirectional	General-purpose I/O pin PA5 on the VDD power domain, multiplexed with ADC0 AIN5, VREFA, TCA0 WO5 and CCL OUT functions.
4	PA6	bidirectional	General-purpose I/O pin PA6 on the VDD power domain, multiplexed with ADC0 AIN6, the DAC0 analog output and AC0 functions.
5	PA7	bidirectional	General-purpose I/O pin PA7 on the VDD power domain, multiplexed with ADC0 AIN7, AC0 AINP0 and CCL LUT1-OUT functions.
6	PB3	passive	Pin PB3 doubles as the TOSC1 connection for the 32.768 kHz external crystal oscillator, multiplexed with AC0 OUT and USART0 RxD.
7	PB2/TOSC2	passive	Pin PB2 doubles as the TOSC2 connection for the 32.768 kHz external crystal oscillator, multiplexed with EVOUT1, AC0 OUT and USART0 TxD.
8	PB1	bidirectional	Digital I/O pin PB1 with ADC0 AIN10 and PTC X4/Y4 functions, also multiplexed to TWI0 SDA and TCA0 WO1.
9	PB0	bidirectional	Digital I/O pin PB0 with ADC0 AIN11 and PTC X5/Y5 functions, also multiplexed to TWI0 SCL and TCA0 WO0.
10	PA0/RESET/UPDI	bidirectional	Pin PA0 is configured through RSTPINCFG as GPIO, RESET or UPDI, and as GPIO its output driver is disabled for 768 OSC32K cycles after a System Reset.
11	PA1	bidirectional	General-purpose I/O pin PA1 with ADC0 AIN1 input, multiplexed to USART0 TxD, SPI0 MOSI, TWI0 SDA and CCL LUT0-IN1.
12	PA2	bidirectional	General-purpose I/O pin PA2 with ADC0 AIN2 input, multiplexed to EVSYS EVOUT0, USART0 RxD, SPI0 MISO, TWI0 SCL and CCL LUT0-IN2.
13	PA3/EXTCLK	bidirectional	Pin PA3 can be used as the external clock input EXTCLK, and is also multiplexed with ADC0 AIN3, SPI0 SCK and TCA0 WO3.
14	GND	power_in	Ground reference for the device supply.
