Electrical characteristics

Figure 30. FT/TC I/O input characteristics
Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to
±8 mA, and sink or
source up to
±20 mA (with a relaxed VOL/VOH) except PC13, PC14 and PC15 which can
sink or source up to
±3mA. When using the PC13 to PC15 GPIOs in output mode, the speed
should not exceed 2 MHz with a maximum load of 30 pF.
In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in Section 6.2. In particular:
The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run
consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating
ΣIVDD (see Table 12).
The sum of the currents sunk by all the I/Os on VSS plus the maximum Run
consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating
ΣIVSS (see Table 12).
