82 / 185 page  Electrical characteristics STM32F405xx, STM32F407xx 82/185 DocID022152 Rev 4 5.3.6 Supply current characteristics The current consumption is a function of several parameters and factors such as the operating voltage, ambient temperature, I/O pin loading, device software configuration, operating frequencies, I/O pin switching rate, program location in memory and executed binary code. The current consumption is measured as described in Figure 22: Current consumption measurement scheme. All Run mode current consumption measurements given in this section are performed using a CoreMark-compliant code. Typical and maximum current consumption The MCU is placed under the following conditions: • At startup, all I/O pins are configured as analog inputs by firmware. • All peripherals are disabled except if it is explicitly mentioned. • The Flash memory access time is adjusted to fHCLK frequency (0 wait state from 0 to 30 MHz, 1 wait state from 30 to 60 MHz, 2 wait states from 60 to 90 MHz, 3 wait states from 90 to 120 MHz, 4 wait states from 120 to 150 MHz, and 5 wait states from 150 to 168 MHz). • When the peripherals are enabled HCLK is the system clock, fPCLK1 = fHCLK/4, and fPCLK2 = fHCLK/2, except is explicitly mentioned. • The maximum values are obtained for VDD = 3.6 V and maximum ambient temperature (TA), and the typical values for TA= 25 °C and VDD = 3.3 V unless otherwise specified.

Guaranteed by design, not tested in production. 2. The reset temporization is measured from the power-on (POR reset or wakeup from VBAT) to the instant when first instruction is read by the user application code. Table 19.
