Electrical characteristics
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 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).
Output voltage levels
Unless otherwise specified, the parameters given in Table 53 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in
Table 24. All I/Os (FT, TTa and TC unless otherwise specified) are CMOS and TTL
compliant.
