79 / 149 page ![]() DocID026289 Rev 6 79/149 STM32F411xC STM32F411xE Electrical characteristics 123 On-chip peripheral current consumption The MCU is placed under the following conditions: • At startup, all I/O pins are in analog input configuration. • All peripherals are disabled unless otherwise mentioned. • The ART accelerator is ON. • Voltage Scale 2 mode selected, internal digital voltage V12 = 1.26 V. • HCLK is the system clock at 84 MHz. fPCLK1 = fHCLK/2, and fPCLK2 = fHCLK. The given value is calculated by measuring the difference of current consumption – with all peripherals clocked off – with only one peripheral clocked on • Ambient operating temperature is 25 °C and VDD=3.3 V.
