1. Data based on a differential IDD measurement between all peripherals OFF and a timer counter running at 16 MHz. The

CPU is in Wait mode in both cases. No IC/OC programmed, no I/O pins toggling. Not tested in production.

2. Data based on a differential IDD measurement between the on-chip peripheral in reset configuration and not clocked and

the on-chip peripheral when clocked and not kept under reset. The CPU is in Wait mode in both cases. No I/O pins toggling.

Not tested in production.

3. Peripherals listed above the IDD(ALL) parameter ON: TIM2, TIM3, TIM4, USART1, SPI1, I2C1, DMA1, WWDG.

4. Data based on a differential IDD measurement between ADC1 in reset configuration and continuous ADC1 conversion.

5. Data based on a differential IDD measurement between COMP1 or COMP2 in reset configuration and COMP1 or COMP2

enabled with static inputs. Supply current of internal reference voltage excluded.

6. Including supply current of internal reference voltage.
