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 the non-standard VOL/VOH specifications given in Table 38.
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 VDD, plus the maximum Run
consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating
IVDD (see Table 7).
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 7).
Output voltage levels
Unless otherwise specified, the parameters given in Table 38 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in
Table 9. All I/Os are CMOS and TTL compliant.

1.
FT = 5V tolerant. To sustain a voltage higher than VDD +0.5 the internal pull-up/pull-down resistors must be disabled.
2.
0.7VDD for 5V-tolerant receiver
3.
FT = Five-volt tolerant.
4.
Hysteresis voltage between Schmitt trigger switching levels. Based on characterization, not tested in production.
5.
With a minimum of 200 mV. Based on characterization, not tested in production.
6.
Leakage could be higher than max. if negative current is injected on adjacent pins.
7.
Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This
MOS/NMOS contribution to the series resistance is minimum (~10% order)
