1. Typical values are measures at TA = 25 °C, VDD = 3.3 V.

2. Add an additional power consumption of 0.8 mA for the ADC and of 0.5 mA for the DAC analog part. In

applications, this consumption occurs only while the ADC is on (ADON bit is set in the ADC_CR2 register).

3. AHB prescaler used to reduce the frequency (when fHCLK > 8 MHz).

On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in Table 18. The MCU is placed

under the following conditions:

● all I/O pins are in input mode with a static value at VDD or VSS (no load)

● 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 VDD supply voltage conditions summarized in

Table 5.
