Typical current consumption

The MCU is placed under the following conditions:

●

VDD = VDDA = 3.3 V

●

All I/O pins available on each package 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), and Flash

prefetch is ON

●

When the peripherals are enabled, fAPB1 = fAHB/2, 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.
