1. 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:

• These GPIOs must not be used as current sources (for example to drive a LED).
• The speed should not exceed 2 MHz with a maximum load of 30 pF

1. After an RTC domain power-up, PC13, PC14 and PC15 operate as GPIOs. Their function then depends on the content of the RTC registers. The RTC registers are not reset upon system reset. For details on how to manage these GPIOs, refer to the RTC domain and RTC register descriptions in the RM0444 reference manual.
2. For the device in SO8N package, the PA0, PA1, and PA2 GPIOs are bonded with NRST on the pin 4. In order not to interfere with device functions, they must not be set in alternate function or in output but remain at all times in input configuration.
3. Pins PA9 and PA10 can be remapped in place of pins PA11 and PA12 (default mapping), using SYSCFG_CFGR1 register.
4. Upon reset, these pins are configured as SW debug alternate functions, and the internal pull-up on PA13 pin and the internal pull-down on PA14 pin are activated.

The definition and values of input/output AC characteristics are given in Figure 18 and Table 51 , respectively.

Unless otherwise specified, the parameters given are derived from tests performed under the ambient temperature and supply voltage conditions summarized in Table 21: General operating conditions .

1. Guaranteed by design.
2. This value represents the I/O capability but the maximum system frequency is limited to 64 MHz.
3. The fall time is defined between 70% and 30% of the output waveform, according to I 2 C specification.

1. Refer to Table 51: I/O AC characteristics .

Stresses above the absolute maximum ratings listed in Table 18 , Table 19 and Table 20 may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

All voltages are defined with respect to V SS .

The operating junction temperature T J must never exceed the maximum given in Table 21: General operating conditions

The maximum junction temperature in °C that the device can reach if respecting the operating conditions, is:
