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.

Maximum current consumption

The MCU is placed under the following conditions:

•

VDD = 3.6 V

•

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 depending on fHCLK frequency and voltage

range

•

Prefetch and 64-bit access are enabled in configurations with 1 wait state

•

When the peripherals are enabled fAPB1 = fAPB2 = fAHB

•

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)

The parameters given in Table 17, Table 13 and Table 14 are derived from tests performed

under ambient temperature and VDD supply voltage conditions summarized in Table 13.
