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 11: Current consumption

measurement scheme.

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 fHCLK frequency (refer to the table “Number of wait states according

to CPU clock (HCLK) frequency” available in the RM0395 reference manual).

•

When the peripherals are enabled fPCLK = fHCLK

The parameters given in Table 26 to Table 39 are derived from tests performed under

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

operating conditions.
