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 = 64 KHz (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. Not tested in production.

2. HSI oscillator is OFF for this measure.

3. These values correspond to the Flash memory configuration interface consumption, which is negligible. To assess true

Flash memory consumption, compare relevant figures, like for example Table 19 and Table 21.
