75 / 192 page  DS12469 Rev 8 75/192 STM32L412xx Electrical characteristics 164 6.1.7 Current consumption measurement Figure 19. Current consumption measurement scheme with and without external SMPS power supply The IDD_ALL parameters given in Table 25 to Table 47 represent the total MCU consumption including the current supplying VDD, VDDA, VDDUSB and VBAT. 6.2 Absolute maximum ratings Stresses above the absolute maximum ratings listed in Table 18: Voltage characteristics, Table 19: Current characteristics and Table 20: Thermal characteristics may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. Device mission profile (application conditions) is compliant with JEDEC JESD47 qualification standard, extended mission profiles are available on demand.
