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 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 Dhrystone 2.1 code.

The current consumption values are derived from the tests performed under ambient

temperature TA=25°C and VDD supply voltage conditions summarized in Table 13: General

operating conditions, unless otherwise specified. The MCU is placed under the following

conditions:

The MCU is placed under the following conditions:

•

VDD = 3.6 V

•

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 OSC_IN input follows the characteristics specified in

Table 26: High-speed external user clock characteristics.
