38 / 115 page  Pinout and pin descriptions STM32F303x6/x8 38/115 DocID025083 Rev 5 - 46 62 PB9 I/O FTf TIM17_CH1, I2C1_SDA, IR_OUT, USART3_TX, COMP2_OUT, CAN_TX, EVENTOUT - 32 47 63 VSS S - - - 148 64 VDD S - - - 1. PC13, PC14 and PC15 are supplied through the power switch. Since the switch sinks only a limited amount of current (3 mA), the use of GPIO PC13 to PC15 in output mode is limited: - The speed should not exceed 2 MHz with a maximum load of 30 pF - These GPIOs must not be used as current sources (e.g. to drive an LED). After the first backup domain power-up, PC13, PC14 and PC15 operate as GPIOs. Their function then depends on the content of the Backup registers which is not reset by the main reset. For details on how to manage these GPIOs, refer to the Battery backup domain and BKP register description sections in the reference manual. 2. Fast ADC channel. 3. These GPIOs offer a reduced touch sensing sensitivity. It is thus recommended to use them as sampling capacitor I/O. Table 14.
