Electrical characteristics

Doc ID 14611 Rev 7

83/123

All I/Os are CMOS and TTL compliant (no software configuration required), their

characteristics consider the most strict CMOS-technology or TTL parameters:

●

For VIH:

–if VDD is in the [2.00 V - 3.08 V] range: CMOS characteristics but TTL included

–if VDD is in the [3.08 V - 3.60 V] range: TTL characteristics but CMOS included

●

For VIL:

–if VDD is in the [2.00 V - 2.28 V] range: TTL characteristics but CMOS included

–if VDD is in the [2.28 V - 3.60 V] range: CMOS characteristics but TTL included

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 8).

●

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 8).

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 10. All I/Os are CMOS and TTL compliant.
