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 V or V (no load)
DD SS
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
●
