Typical current consumption
The MCU is placed under the following conditions:
V
DD
= V
DDA
= 3.3 V
All I/O pins are in analog input configuration
The Flash access time is adjusted to f
HCLK
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, f
PCLK
= f
HCLK
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
