PIC12F508T-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 for logic and I/O pins. Operating range 2.0V to 5.5V.
2	GP5/OSC1/CLKIN	bidirectional	Multiplexed pin. GP5: Bidirectional I/O with software-programmable weak pull-up and wake-on-change. OSC1: Crystal input in XT/LP crystal oscillator modes. CLKIN: External clock source input in EXTRC/EC modes.
3	GP4/OSC2	bidirectional	Multiplexed pin. GP4: Bidirectional I/O (TTL in / CMOS out). OSC2: Oscillator crystal output - connects to crystal/resonator in XT and LP crystal oscillator modes; functions as GPIO in other oscillator modes.
4	GP3/MCLR/VPP	input	Multiplexed pin. GP3: Input-only pin with software-programmable weak pull-up and wake-on-change. MCLR: Active-low Master Clear (Reset); voltage must not exceed VDD during normal operation or the device will enter Programming mode. Weak pull-up always on when configured as MCLR. VPP: High-voltage programming input during ICSP.
5	GP2/T0CKI	bidirectional	Multiplexed pin. GP2: Bidirectional I/O (TTL in / CMOS out). T0CKI: External clock input to Timer0 (Schmitt Trigger input). Selection determined by T0CS bit in the OPTION register.
6	GP1/ICSPCLK	bidirectional	Multiplexed pin. GP1: Bidirectional I/O with software-programmable weak pull-up and wake-on-change (TTL in / CMOS out). ICSPCLK: In-Circuit Serial Programming clock pin (Schmitt Trigger input).
7	GP0/ICSPDAT	bidirectional	Multiplexed pin. GP0: Bidirectional I/O with software-programmable weak pull-up and wake-on-change (TTL in / CMOS out). ICSPDAT: In-Circuit Serial Programming data pin (Schmitt Trigger input).
8	VSS	power_in	Ground reference for logic and I/O pins.
