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.
