Electrical characteristics

STM32WBA50KG

86/110

DS14688 Rev 1

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 15.

Figure 15. I/O input characteristics (all I/Os except PH3)

Output driving current

The I/Os can sink or source up to ±8 mA, 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 5.2.

•

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 23).

•

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 23).

Output voltage levels

Unless otherwise specified, the parameters given in Table 62 are at ambient temperature

and under the supply voltage conditions summarized in Table 26. All I/Os are CMOS- and

TTL-compliant.
