Pinout

Pin Name Type Function
1 VBAT power_in Battery backup supply input of 1.8 to 3.6 V that powers ERTC, LEXT and BPR when VDD is absent.
2 PC13 bidirectional GPIO PC13 (TAMPER-RTC) powered through a power switch that can source only 3 mA, so it must not drive current-source loads such as LEDs when used as output.
3 PC14 bidirectional GPIO PC14 (LEXT_IN) powered through a power switch limited to 3 mA source current, so it must not drive current-source loads when used as output.
4 PC15 bidirectional GPIO PC15 (LEXT_OUT) powered through a power switch limited to 3 mA source current, so it must not drive current-source loads when used as output.
5 PD0 bidirectional GPIO PD0 whose default function after reset is HEXT_IN for a 4 to 25 MHz crystal oscillator input, reconfigurable to PD0 by software.
6 PD1 bidirectional GPIO PD1 whose default function after reset is HEXT_OUT for a 4 to 25 MHz crystal oscillator output, reconfigurable to PD1 by software.
7 NRST bidirectional Active-low reset pin with internal pull-up RPU of 30 to 50 kOhm (typ. 40 kOhm); low level must last at least 66.7 us to be recognized as a valid reset.
8 VSSA/VREF- power_in Analog ground for ADC and CMP, which must be at the same potential as VSS.
