Electrical characteristics

STM32L151xC STM32L152xC

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 the non-standard VOL/VOH specifications given in Table 44.

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 VDD, plus the maximum Run

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

IVDD(Σ) (see Table 12).

• 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

IVSS(Σ) (see Table 12).

Output voltage levels

Unless otherwise specified, the parameters given in Table 44 are derived from tests

performed under the conditions summarized in Table 14. All I/Os are CMOS and TTL

compliant.
