1. Code and data processing running from SRAM1 using boot pins.

2. Guaranteed based on test during characterization.

3. When analog peripheral blocks such as ADCs, DACs, HSE, LSE, HSI, or 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.

5. Tested in production.

6. Overdrive OFF
