Electrical characteristics

STM32L475xx

128/193

DocID027692 Rev 2

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 Figure 19 for standard I/Os, and in Figure 19 for

5 V tolerant I/Os.

Figure 19. 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).

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:

•

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 19: Voltage 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 19: Voltage characteristics).
