PIC12F683T-I from Microchip, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VDD	power_in	Positive supply for the logic and I/O pins. Operating range 2.0V to 5.5V.
2	GP5/T1CKI/OSC1/CLKIN	bidirectional	General purpose I/O GP5 with interrupt-on-change and weak pull-up. Alternate functions: Timer1 external clock input (T1CKI), crystal oscillator input (OSC1), or external clock input (CLKIN).
3	GP4/AN3/T1G/OSC2/CLKOUT	bidirectional	General purpose I/O GP4 with interrupt-on-change and weak pull-up. Alternate functions: ADC channel 3 analog input (AN3), Timer1 external gate input (T1G, active low), crystal oscillator output (OSC2), or FOSC/4 clock output (CLKOUT).
4	GP3/MCLR/VPP	input	Input-only general purpose pin GP3 with interrupt-on-change. Alternate functions: active-low master clear reset input (MCLR) with weak pull-up when enabled, and high-voltage programming input (VPP) during ICSP.
5	GP2/AN2/T0CKI/INT/COUT/CCP1	bidirectional	General purpose I/O GP2 with interrupt-on-change and weak pull-up. Alternate functions: ADC channel 2 (AN2), comparator output (COUT), Timer0 external clock input (T0CKI), external interrupt (INT), Capture/Compare/PWM (CCP1).
6	GP1/AN1/CIN-/VREF/ICSPCLK	bidirectional	General purpose I/O GP1 with interrupt-on-change and weak pull-up. Alternate functions: ADC channel 1 (AN1), analog comparator inverting input (CIN-), external ADC voltage reference (VREF), and ICSP programming clock (ICSPCLK).
7	GP0/AN0/CIN+/ICSPDAT/ULPWU	bidirectional	General purpose I/O GP0 with interrupt-on-change and weak pull-up. Alternate functions: ADC channel 0 (AN0), analog comparator non-inverting input (CIN+), ICSP programming data (ICSPDAT), and Ultra Low-Power Wake-up input (ULPWU).
8	VSS	power_in	Ground reference for logic and I/O pins.
