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 13: Current characteristics).

● 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 13: Current characteristics).

Output voltage levels

Unless otherwise specified, the parameters given in Table 46 are derived from tests

performed under ambient temperature and VDD supply voltage conditions summarized in

Table 15: General operating conditions. All I/Os are CMOS and TTL compliant (FT, TTa or

TC unless otherwise specified).

1. The IIO current sunk by the device must always respect the absolute maximum rating specified in Table 13:

Current characteristics and the sum of IIO (I/O ports and control pins) must not exceed IVSS.

2. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52.

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

Table 13: Current characteristics and the sum of IIO (I/O ports and control pins) must not exceed IVDD.

4. Data based on design simulation only. Not tested in production.
