1. Based on characterization, tested in production at VDD max and fHCLK max with peripherals enabled.
2. External clock is 4 MHz and PLL is on when fHCLK > 25 MHz.
3. When analog peripheral blocks such as (ADCs, DACs, HSE, LSE, HSI,LSI) are on, an additional power consumption
should be considered.
4. When the ADC is ON (ADON bit set in the ADC_CR2 register), add an additional power consumption of 1.6 mA per ADC
for the analog part.
