Typical current consumption

The MCU is placed under the following conditions:

● VDD=VDDA=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 above)

● Prefetch is ON when the peripherals are enabled, otherwise it is OFF

● When the peripherals are enabled, fPCLK = fHCLK

● PLL is used for frequencies greater than 8 MHz

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

500 kHz respectively

● A development tool is connected to the board and the parasitic pull-up current is around

30 µA
