STM32F051x4 STM32F051x6 STM32F051x8 Electrical characteristics

On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in Table 31. The MCU is placed

under the following conditions:

• All I

/O pins are in analog mode

• All peripherals are disabled unless otherwise mentioned

• The given value is calculated by measuring the current consumption

– with all peripherals clocked off

– with only one peripheral clocked on

• Ambient operating temperature and supply voltage conditions summarized in Table 17:
