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 Dhrystone 2.1 code, unless otherwise
specified.
The current consumption values are derived from the tests performed under ambient
temperature T_A=25°C and V_DD supply voltage conditions summarized in Table 12: General
operating conditions, unless otherwise specified.
Maximum current consumption
The MCU is placed under the following conditions:
• V_DD = 3.6 V
• All I/O pins are in input mode with a static value at V_DD or V_SS (no load).
• All peripherals are disabled except when explicitly mentioned.
• The Flash memory access time is adjusted depending on f_HCLK frequency and voltage
range.
• Prefetch and 64-bit access are enabled in configurations with 1 wait state.
• When the peripherals are enabled f_APB1 = f_APB2 = f_AHB.
• When fHCLK > 8 MHz, PLL is ON and PLL inputs are equal to HSI = 8 MHz (if internal
clock is used) or HSE = 8 MHz (if HSE bypass mode is used).
