1. Data based on differential I
DD
measurement between all peripherals OFF an one peripheral with clock enabled, in the
following conditions: f
HCLK
= 32 MHz (Range 1), f
HCLK
= 16 MHz (Range 2), f
HCLK
= 4 MHz (Range 3), f
HCLK
= 64kHz
(Low power run/sleep), f

APB2
= f
HCLK
, default prescaler value for each peripheral. The CPU is in Sleep
mode in both cases. No I/O pins toggling. Not tested in production.
2. HSI oscillator is OFF for this measure.
3. Data based on a differential I
DD
measurement between ADC in reset configuration and continuous ADC conversion (HSI
consumption not included).
4. Data based on a differential I
DD
measurement between DAC in reset configuration and continuous DAC conversion of
V
DD
/2. DAC is in buffered mode, output is left floating.
5. Including supply current of internal reference voltage.
