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. 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 22).

•

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 22).
