1. Data based on differential IDD measurement between all peripherals OFF an one peripheral with clock enabled, in the

following conditions: fHCLK = 32 MHz (Range 1), fHCLK = 16 MHz (Range 2), fHCLK = 4 MHz (Range 3), fHCLK = 64kHz

(Low power run/sleep), fAPB1 = fHCLK, fAPB2 = fHCLK, default prescaler value for each peripheral. The CPU is in Sleep

mode in both cases. No I/O pins toggling.

2. HSI oscillator is OFF for this measure.

3. Data based on a differential IDD measurement between ADC in reset configuration and continuous ADC conversion (HSI

consumption not included).

4. Data based on a differential IDD measurement between DAC in reset configuration and continuous DAC conversion of

VDD/2. DAC is in buffered mode, output is left floating.

5. Including supply current of internal reference voltage.
