Figure 36. I/O input characteristics (all I/Os except BOOT0)

Output driving current

The GPIOs (except PC13, PC14, PC15) can sink or source up to ± 8 mA, and sink or source up to ± 20 mA (with

a relaxed VOL/VOH). PC13, PC14, PC15 are limited in source capability: +3 mA shared between the three I/Os.

These GPIOs have the same sink capability than other GPIOs.

In the user application, the number of I/O pins tat can drive current must be limited to respect the absolute

maximum rating specified in Section 5.2: Absolute maximum ratings:

•

The sum of the currents sourced by all the I/Os on VDDIOx, plus the maximum consumption of the MCU

sourced on VDD, cannot exceed the absolute maximum rating ∑IVDD (see Table 25. Current

characteristics).

•

The sum of the currents sunk by all the I/Os on VSS, plus the maximum consumption of the MCU sunk on

VSS, cannot exceed the absolute maximum rating ∑IVSS (see Table 25. Current characteristics).

Output voltage levels

Unless otherwise specified, the parameters given in the table below are derived from tests performed under the

ambient temperature and supply voltage conditions summarized in Table 27. All I/Os are CMOS- and TTL-

compliant (FT or TT unless otherwise specified).
