70 / 135 page  Electrical characteristics STM32F401xD STM32F401xE 70/135 Table 28. Typical and maximum current consumption in Stop mode - VDD=3.3 V Symbol Parameter Conditions Typ Max(1) Unit TA = 25 °C TA = 25 °C TA = 85 °C TA = 105 °C IDD_STOP Main regulator usage Flash in Stop mode, all oscillators OFF, no independent watchdog 111 140 450 670 µA Low power regulator usage 42 65 330 560 Main regulator usage Flash in Deep power down mode, all oscillators OFF, no independent watchdog 73 100 360 560 Low power regulator usage 12 36 270 520 Low power low voltage regulator usage 10 28 230 470 1. Guaranteed by characterization, not tested in production. Table 29. Typical and maximum current consumption in Standby mode - VDD=1.8 V Symbol Parameter Conditions Typ(1) Max(2) Unit TA = 25 °C TA = 25 °C TA = 85 °C TA = 105 °C IDD_STBY Supply current in Standby mode Low-speed oscillator (LSE) and RTC ON 2.4 4.0 12.0 24.0 µA RTC and LSE OFF 1.8 3.0(3) 11.0 23.0(3) 1. When the PDR is OFF (internal reset is OFF), the typical current consumption is reduced by 1.2 µA. 2. Guaranteed by characterization, not tested in production unless otherwise specified. 3. Guaranteed by test in production. Table 30. Typical and maximum current consumption in Standby mode - VDD=3.3 V Symbol Parameter Conditions Typ(1) Max(2) Unit TA = 25 °C TA = 25 °C TA = 85 °C TA = 105 °C IDD_STBY Supply current in Standby mode Low-speed oscillator (LSE) and RTC ON 2.8 5.0 14.0 28.0 µA RTC and LSE OFF 2.1 4.0(3) 13.0 27.0(3) 1. When the PDR is OFF (internal reset is OFF), the typical current consumption is reduced by 1.2 µA. 2. Guaranteed by characterization, not tested in production unless otherwise specified. 3. Guaranteed by test in production. |
