Typical current consumption
The MCU is placed under the following conditions:
 V
DD
= V
DDA
= 3.3 V
 All I/O pins available on each package are in analog input configuration
 The Flash access time is adjusted to f
HCLK
frequency (0 wait states from 0 to 24 MHz,
1 wait state from 24 to 48 MHz and 2 wait states from 48 MHz to 72 MHz), and Flash
prefetch is ON
 When the peripherals are enabled, f
APB1
= f
AHB/2
, f
APB2
= f
AHB
 PLL is used for frequencies greater than 8 MHz
 AHB prescaler of 2, 4, 8,16 and 64 is used for the frequencies 4 MHz, 2 MHz, 1 MHz,
500 kHz and 125 kHz respectively.
