Electrical characteristics
STM32F37xxx
On-chip peripheral current consumption
The MCU is placed under the following conditions:
• All I/O pins are in analog input configuration.
• All peripherals are disabled unless otherwise mentioned.
• The given value is calculated by measuring the current consumption
– with all peripherals clocked off;
– with only one peripheral clocked on.
• Ambient operating temperature at 25°C and VDD = VDDA= 3.3 Volts.
