Supply current characteristics
The current consumption is a function of several parameters and factors such as the
operating voltage, 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 14: 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 the Dhrystone 2.1 code, unless
otherwise specified. The current consumption values are derived from tests performed
under ambient temperature TA = 25 °C and VDD supply voltage conditions summarized in
Table 14: General operating conditions, unless otherwise specified.
The MCU is placed under the following conditions:
• All I/O pins are configured in analog input mode
• All peripherals are disabled except when explicitly mentioned.
• The Flash memory access time, 64-bit access and prefetch is adjusted depending on
fHCLK frequency and voltage range to provide the best CPU performance.
• When the peripherals are enabled fAPB1 = fAPB2 = fAHB.
• When PLL is ON, the PLL inputs are equal to HSI = 16 MHz (if internal clock is used) or
HSE = 16 MHz (if HSE bypass mode is used).
• The HSE user clock applied to OSCI_IN input follows the characteristic specified in
Table 27: High-speed external user clock characteristics.
• For maximum current consumption VDD = VDDA = 3.6 V is applied to all supply pins.
• For typical current consumption VDD = VDDA = 3.0 V is applied to all supply pins if not
specified otherwise.
