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 power consumption in low power mode.

3. Compatibility issue on alternate function pin PE4 SAI1_SD_A and PE6 SAI1_FS_A: Pins have been swapped versus other

MCUs supporting those alternate SAI functions on those pins

4. PC13, PC14 and PC15 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 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).

5. 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

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

7. Incompatibility issue on alternate function with other MCUs supporting UART4: UART4_TX wrongly mapped to PD10

instead of PC10
