1. Typical values are measures at TA = 25 °C, VDD = 3.3 V.
2. Add an additional power consumption of 0.8 mA per ADC for the analog part. In applications, this
consumption occurs only while the ADC is on (ADON bit is set in the ADC_CR2 register).
3. External clock is 8 MHz and PLL is on when fHCLK > 8 MHz.
On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 19. The MCU is placed
under the following conditions:

all peripherals are disabled unless otherwise mentioned
the given value is calculated by measuring the current consumption
