Typical current consumption

The MCU is placed under the following conditions:

• VDD = VDDA = VDDSD12 = VDDSD3 = 3.3 V

• All I/O pins are in analog input configuration

• The Flash access time is adjusted to fHCLK frequency (0 wait states from 0 to 24 MHz,

1 wait state from 24 to 48 MHz and 2 wait states from 48 MHz to 72 MHz)

• Prefetch is ON

• When the peripherals are enabled, fAPB1 = fAHB, fAPB2 = fAHB

• PLL is used for frequencies greater than 8 MHz

• AHB prescaler of 2, 4, 8, 16 and 64 is used for the frequencies 4 MHz, 2 MHz, 1 MHz,

500 kHz and 125 kHz respectively
