Electrical characteristics
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
