Doc ID 023683 Rev 1
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
