Output driving current
The GPIOs (general-purpose inputs/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 5.2:
• 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
IVDD (see Table 6).
• 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
IVSS (see Table 6).
