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

IVDD (see Table 16).



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 16).

Output voltage levels

Unless otherwise specified, the parameters given in Table 63 are derived from tests

performed under ambient temperature and VDD supply voltage conditions summarized in

Table 18

. All I/Os (FT, TTa and TC unless otherwise specified) are CMOS and TTL

compliant.

1. The IIO current sunk by the device must always respect the absolute maximum rating specified in Table 16 and the sum of

IIO (I/O ports and control pins) must not exceed IIO(PIN).

2. The IIO current sourced by the device must always respect the absolute maximum rating specified in Table 16 and the sum

of IIO (I/O ports and control pins) must not exceed IIO(PIN).

3. Data based on design simulation.
