Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to +/-8 mA, and sink
+20 mA (with a relaxed V ).
OL
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 V
plus the maximum Run
DD,
consumption of the MCU sourced on V
cannot exceed the absolute maximum rating
DD,
I
(see Table 6).
