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 the non-standard VOL/VOH specifications given in Table 44.

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 12).

•

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 12).

Output voltage levels

Unless otherwise specified, the parameters given in Table 44 are derived from tests

performed under ambient temperature and VDD supply voltage conditions summarized in

Table 14. All I/Os are CMOS and TTL compliant.

1. The IIO current sunk by the device must always respect the absolute maximum rating specified in Table 12 and the sum of

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

2. Guaranteed by test in production.

3. The IIO current sourced by the device must always respect the absolute maximum rating specified in Table 12 and the sum

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

4. Guaranteed by characterization results.
