PIC12F629T-I from Microchip Tech, 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. Operating range 2.0 V to 5.5 V. Bypass locally with a 100 nF ceramic capacitor to VSS.
2	GP5/T1CKI/OSC1/CLKIN	bidirectional	GP5: bidirectional I/O with interrupt-on-change and programmable weak pull-up (TTL in, CMOS out). T1CKI: Timer1 external clock input (ST). OSC1: crystal/resonator connection to the internal oscillator. CLKIN: external clock input / RC oscillator connection (ST).
3	GP4/T1G/OSC2/CLKOUT	bidirectional	GP4: bidirectional I/O with interrupt-on-change and programmable weak pull-up (TTL in, CMOS out). T1G: Timer1 gate input (ST). OSC2: crystal/resonator connection. CLKOUT: FOSC/4 output when configured for RC or INTOSC-CLKOUT modes.
4	GP3/MCLR/VPP	input	GP3: input-only port with interrupt-on-change and programmable weak pull-up (TTL). MCLR: active-low Master Clear reset input (ST). VPP: high-voltage (typ. 12-13.5 V) programming supply during ICSP.
5	GP2/T0CKI/INT/COUT	bidirectional	GP2: bidirectional I/O with interrupt-on-change and programmable weak pull-up (ST in, CMOS out). T0CKI: Timer0 external clock input (ST). INT: external interrupt input (ST). COUT: analog comparator output (CMOS).
6	GP1/CIN-/ICSPCLK	bidirectional	GP1: bidirectional I/O with interrupt-on-change and programmable weak pull-up (TTL in, CMOS out). CIN-: analog comparator inverting input. ICSPCLK: In-Circuit Serial Programming clock (ST).
7	GP0/CIN+/ICSPDAT	bidirectional	GP0: bidirectional I/O with interrupt-on-change and programmable weak pull-up (TTL in, CMOS out). CIN+: analog comparator non-inverting input. ICSPDAT: In-Circuit Serial Programming data I/O (ST/CMOS).
8	VSS	power_in	Ground / negative supply reference (0 V).
