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 | PC13 | bidirectional | General-purpose I/O, 5 V tolerant (FT). Supplied through the RTC power switch - limited to <=2 MHz, <=30 pF, no current-source drive; not for driving LEDs. |+| 2 | PC14-OSC32_IN | bidirectional | GPIO PC14 (FT) muxed with 32.768 kHz LSE crystal oscillator input (OSC32_IN). Supplied via the RTC power switch - same 2 MHz/30 pF drive limits as PC13. |+| 3 | PC15-OSC32_OUT | bidirectional | GPIO PC15 (FT) muxed with 32.768 kHz LSE crystal oscillator output (OSC32_OUT). Supplied via the RTC power switch - 2 MHz/30 pF drive limits apply. |+| 4 | VBAT | power_in | RTC / backup domain supply. Connect to 1.55-3.6 V backup battery, or tie to VDD if unused. Powers RTC, LSE oscillator and backup registers when VDD is absent. |+| 5 | VREF+ | power_in | ADC/DAC positive reference input, 1.62 V to VDDA. Can be internally driven from VREFBUF (VREF_OUT) as the additional function. |+| 6 | VDD/VDDA | power_in | Combined digital (VDD) and analog (VDDA) supply, 1.7 V to 3.6 V. Decouple with 100 nF close to pin; add a 1-10 µF bulk cap near the package. |+| 7 | VSS/VSSA | power_in | Combined digital (VSS) and analog (VSSA) ground return. Tie to the board ground plane. |+| 8 | PF0-OSC_IN | bidirectional | GPIO PF0 (FT) muxed with the HSE crystal oscillator input (OSC_IN, 4-48 MHz). |+| 9 | PF1-OSC_OUT | bidirectional | GPIO PF1 (FT) muxed with the HSE crystal oscillator output (OSC_OUT). |+| 10 | PF2-NRST | bidirectional | Bidirectional device reset pin with an internal weak pull-up (also configurable as GPIO PF2 or MCO). Drive low to reset; a 100 nF decoupling cap is recommended. |+| 11 | PA0 | bidirectional | General-purpose I/O, 5 V tolerant with analog switch (FT_a).
