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 that can drive current must be limited to

respect the absolute maximum rating specified in Section 5.2. In particular:

•

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 18).

•

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 18).

Output voltage levels

Unless otherwise specified, the parameters given in Table 59 and Table 61 are derived from

tests performed under ambient temperature and VDD supply voltage conditions summarized

in Table 20. All I/Os are CMOS and TTL compliant.
