85 / 204 page  DS8626 Rev 9 85/203 STM32F405xx, STM32F407xx Electrical characteristics Table 20. Typical and maximum current consumption in Run mode, code with data processing running from Flash memory (ART accelerator enabled) or RAM (1) Symbol Parameter Conditions fHCLK Typ Max(2) Unit TA = 25 °C TA = 85 °C TA = 105 °C IDD Supply current in Run mode External clock(3), all peripherals enabled(4)(5) 168 MHz 87 102 109 mA 144 MHz 67 80 86 120 MHz 56 69 75 90 MHz 44 56 62 60 MHz 30 42 49 30 MHz 16 28 35 25 MHz 12 24 31 16 MHz(6) 920 28 8 MHz 5 17 24 4 MHz 3 15 22 2 MHz 2 14 21 External clock(3), all peripherals disabled(4)(5) 168 MHz 40 54 61 144 MHz 31 43 50 120 MHz 26 38 45 90 MHz 20 32 39 60 MHz 14 26 33 30 MHz 8 20 27 25 MHz 6 18 25 16 MHz(6) 516 24 8 MHz 3 15 22 4 MHz 2 14 21 2 MHz 2 14 21 1. Code and data processing running from SRAM1 using boot pins. 2. Guaranteed by characterization, tested in production at VDD max and fHCLK max with peripherals enabled. 3. External clock is 4 MHz and PLL is on when fHCLK > 25 MHz. 4. When the ADC is ON (ADON bit set in the ADC_CR2 register), add an additional power consumption of 1.6 mA per ADC for the analog part. 5. When analog peripheral blocks such as ADCs, DACs, HSE, LSE, HSI, or LSI are ON, an additional power consumption should be considered. 6. In this case HCLK = system clock/2. |
