STM32F302xx/STM32F303xx
Electrical characteristics
Typical current consumption
The MCU is placed under the following conditions:
●
●
●
V
= V
= 3.3 V
DDA
DD
All I/O pins available on each package are in analog input configuration
The Flash access time is adjusted to f frequency (0 wait states from 0 to 24 MHz,
HCLK
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
= f
, f
= f
APB1
AHB/2 APB2 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.
