1. PC13, PC14 and PC15 are supplied through the power switch (by VSW). Since the switch only sinks a limited amount of current (3 mA), the use of PC13 to PC15 GPIOs in output

mode is limited. PC13 speed must not exceed 2 MHz with a maximum load of 30 pF. Refer to FT_o electrical characteristics for PC14, PC15. These GPIOs must not be used as

current sources (for example to drive a LED).

2. After a backup domain power-up, PC13, PC14 and PC15 operate as GPIOs. Their function depends on the content of the RTC registers that are not reset by the system reset. For

details on how to manage these GPIOs, refer to the backup domain and RTC register descriptions in the product reference manual.

3. After reset, this pin is configured as JTAG/SWD alternate functions. The internal pull-up on PA15, PA13, PB4 pins and the internal pull-down on PA14 pin are activated.

4. Boot for all packages except for WLCSP68 SMPS-G package.

5. Boot only for WLCSP68 SMPS-G package.

6. Power supply is VDDIO2.

7. On the UQFN32 package the pin PB7 is internally connected to BOOT0, and therefore it is denoted as PB7-BOOT0.
