Figure 31. 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 14).

•

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 14).

Output voltage levels

Unless otherwise specified, the parameters given in Table 57 are derived from tests

performed under ambient temperature and VDD supply voltage conditions summarized in

Table 16. All I/Os are CMOS and TTL compliant.
