1. Function availability depends on the chosen device.

2. NC (not-connected) pins are not bonded. They must be configured by software to output push-pull and forced to “0” in the

output data register to avoid extra current consumption in low power modes.

3. PC13, PC14, PC15 and PI8 are supplied through the power switch. Since the switch only sinks a limited amount of current

(3 mA), the use of GPIOs PC13 to PC15 and PI8 in output mode is limited:

- The speed should not exceed 2 MHz with a maximum load of 30 pF.

- These I/Os must not be used as a current source (e.g. to drive an LED).

4. Main function after the first backup domain power-up. Later on, it depends on the contents of the RTC registers even after

reset (because these registers are not reset by the main reset). For details on how to manage these I/Os, refer to the RTC

www.st.com.

FT = 5 V tolerant except when in analog mode or oscillator mode (for PC14, PC15, PH0 and PH1).
