Electrical characteristics
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. 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
IVDD (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
IVSS (see Table 12).
Output voltage levels
Unless otherwise specified, the parameters given in Table 48 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. PC13, PC14, PC15 and PI8 are supplied through the power switch. Since the switch only sinks a limited
amount of current (3 mA), the use of GPIOs PC13 to PC15 and PI8 in output mode is limited: the speed
should not exceed 2 MHz with a maximum load of 30 pF and these I/Os must not be used as a current
source (e.g. to drive an LED).
