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 memory access time is adjusted to fHCLK frequency:

– 0 wait state and Prefetch OFF from 0 to 24 MHz

– 1 wait state and Prefetch ON above 24 MHz

• 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
