Electrical characteristics

253

All I/Os are CMOS- and TTL-compliant (no software configuration required). Their

characteristics cover more than the strict CMOS-technology or TTL parameters. The

coverage of these requirements is shown in the figure below.

Figure 34. I/O input characteristics (all I/Os except BOOT0 and FT_c)

Output driving current

The GPIOs (except PC13, PC14, PC15) can sink or source up to ±8 mA, and sink or source

up to ± 20 mA (with a relaxed VOL/VOH). PC13, PC14, PC15 are limited in source capability:

+3 mA shared between the three I/Os. These GPIOs have the same sink capability than

other GPIOs.

In the user application, the number of I/O pins tat can drive current must be limited to

respect the absolute maximum rating specified in Section 5.2: Absolute maximum ratings:

•

The sum of the currents sourced by all the I/Os on VDDIOx, plus the maximum

consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating

ΣIVDD (see Table 30: Current characteristics).

•

The sum of the currents sunk by all the I/Os on VSS, plus the maximum consumption of

the MCU sunk on VSS, cannot exceed the absolute maximum rating ΣIVSS

(see Table 30: Current characteristics).
