1. Based on characterization, tested in production at V_DD max and f_HCLK max with peripherals enabled.
2. External clock is 4 MHz and PLL is on when f_HCLK > 25 MHz.
3. Add an additional power consumption of 1.6 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).
