61 / 141 page  DS9895 Rev 8 61/141 STM32F301x6 STM32F301x8 Electrical characteristics 115 6.3.4 Embedded reference voltage The parameters given in Table 27 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 23. 6.3.5 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 13: Current consumption measurement scheme. All Run-mode current consumption measurements given in this section are performed with a reduced code that gives a consumption equivalent to CoreMark code. Note: The total current consumption is the sum of IDD and IDDA. Table 27.
