Electrical characteristics
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 10: 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.
Typical and maximum current consumption
The MCU is placed under the following conditions:
• All I/O pins are in input mode with a static value at VDD or VSS (no load)
• All peripherals are disabled except when explicitly mentioned
• The Flash memory access time is adjusted to the fHCLK frequency (0 wait state from 0
to 24 MHz, 1 wait state from 24 to 48 MHz and 2 wait states from 48 MHz to 72 MHz)
• Prefetch in ON (reminder: this bit must be set before clock setting and bus prescaling)
• When the peripherals are enabled fAPB1 = fAHB/2 , fAPB2 = fAHB
• When fHCLK > 8 MHz PLL is ON and PLL inputs is equal to HSI/2 = 4 MHz (if internal
clock is used) or HSE = 8 MHz (if HSE bypass mode is used)
The parameters given in Table 28 to Table 34 are derived from tests performed under
ambient temperature and supply voltage conditions summarized in Table 22.
