Typical current consumption
The MCU is placed under the following conditions:
• V
DD
= V
DDA
= V
DDSD12
= V
DDSD3
= 3.3 V
• All I/O pins 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)
• Prefetch is ON
• When the peripherals are enabled, f
APB1
= f
AHB
, 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
