Electrical characteristics
STM32F102x4, STM32F102x6
Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to +/-8 mA, and sink
+20 mA (with a relaxed VOL).
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).
Output voltage levels
Unless otherwise specified, the parameters given in Table 34 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in
Table 8. All I/Os are CMOS and TTL compliant.
Table 34.
