Figure 30. FT I/O input 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) except PC13, PC14 and PC15 which can
sink or source up to
±3mA. When using the PC13 to PC15 GPIOs in output mode, the speed
should not exceed 2 MHz with a maximum load of 30 pF.
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. 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 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 55 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.
