Electrical characteristics STM32F412xE/G
82/193 DocID028087 Rev 4
Typical and maximum current consumption
The MCU is placed under the following conditions:
• All I/O pins are in input mode with a static value at VDD or VSS (no load).
• All peripherals are disabled except if it is explicitly mentioned.
• The Flash memory access time is adjusted to both f
HCLK
frequency and VDD ranges
(refer to Table 16: Features depending on the operating power supply range).
• The voltage scaling is adjusted to f
HCLK
frequency as follows:
– Scale 3 for f
HCLK
≤ 64 MHz
– Scale 2 for 64 MHz < f
HCLK
≤ 84 MHz
– Scale 1 for 84 MHz < f
HCLK
≤ 100 MHz
• The system clock is HCLK, f
PCLK1
= f
HCLK
/2, and f
PCLK2
= f
HCLK
.
• External clock is 4 MHz and PLL is ON except if it is explicitly mentioned.
• The maximum values are obtained for V
DD
= 3.6 V and a maximum ambient
temperature (T
A
), and the typical values for T
A
= 25 °C and V
DD
= 3.3 V unless
otherwise specified.

1. Based on characterization, not tested in production unless otherwise specified
2. When analog peripheral blocks such as ADC, HSE, LSE, HSI, or LSI are ON, an additional power consumption has to be
considered.
3. When the ADC is ON (ADON bit set in the ADC_CR2 register), add an additional power consumption of 1.6 mA for the
analog part.
