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 12: Current consumption

measurement scheme.

All the run-mode current consumption measurements given in this section are performed

with a CoreMark code.

Typical and maximum current consumption

The MCU is placed under the following conditions:



All I/O pins are in analog input mode.



All peripherals are disabled except when explicitly mentioned.



The Flash memory access time is adjusted with the minimum wait states number,

depending on the fACLK frequency (refer to the table “Number of wait states according to

CPU clock (frcc_c_ck) frequency and VCORE range” available in the reference manual).



When the peripherals are enabled, the AHB clock frequency is the CPU frequency

divided by 2 and the APB clock frequency is AHB clock frequency divided by 2.

The parameters given in Table 28 to Table 36 are derived from tests performed under

ambient temperature and supply voltage conditions summarized in Table 22: General

operating conditions.
