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).

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:

• The sum of the currents sourced by all the I/Os on all VDD_x and VDDSDx, plus the

maximum Run consumption of the MCU sourced on VDD cannot exceed the absolute

maximum rating ΣIVDD (see Table 20).

• The sum of the currents sunk by all the I/Os on all VSS_x and VSSSD, plus the

maximum Run consumption of the MCU sunk on VSS cannot exceed the absolute

maximum rating ΣIVSS (see Table 20).
