STM32WB15CC

Electrical characteristics

115

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

characteristics cover more than the strict CMOS-technology or TTL parameters, as shown

in Figure 20 .

Figure 20. 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 that 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 VDD, plus the maximum

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

ΣIVDD (see Table 17: 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 17: Voltage characteristics).

Output voltage levels

Unless otherwise specified, the parameters given in the table below are derived from tests

performed under the ambient temperature and supply voltage conditions summarized in

Table 21: General operating conditions. All I/Os are CMOS- and TTL-compliant (FT or TT

unless otherwise specified).
