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.
