PIC12F509T-I from Microchip Tech, in a SOIC-8. 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 | Positive supply for logic and I/O pins, with a supply range of 2.0V to 5.5V. |
| 2 | GP5/OSC1/CLKIN | bidirectional | Bidirectional I/O pin that also serves as oscillator crystal input (OSC1) or external clock source input (CLKIN). |
| 3 | GP4/OSC2 | bidirectional | Bidirectional I/O pin that also serves as oscillator crystal output (OSC2) in XT and LP modes, and as GPIO in other modes. |
| 4 | GP3/MCLR/VPP | input | Input-only pin with optional weak pull-up and wake-up on pin change, configurable as active-low Master Clear (Reset) or programming voltage input VPP; voltage on MCLR/VPP must not exceed VDD during normal operation or the device enters Programming mode. |
| 5 | GP2/T0CKI | bidirectional | Bidirectional I/O pin that also serves as the clock input to TMR0. |
| 6 | GP1/ICSPCLK | bidirectional | Bidirectional I/O pin with software-programmable weak pull-up and wake-up from Sleep on pin change, also the In-Circuit Serial Programming clock pin. |
| 7 | GP0/ICSPDAT | bidirectional | Bidirectional I/O pin with software-programmable weak pull-up and wake-up from Sleep on pin change, also the In-Circuit Serial Programming data pin. |
| 8 | VSS | power_in | Ground reference for logic and I/O pins. |
