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.

All Run-mode current consumption measurements given in this section are performed with a

reduced code that gives a consumption equivalent to CoreMark code.

The data provided apply to standard dies only.

Typical and maximum current consumption

The MCU is placed under the following conditions:

● 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 to the fHCLK frequency (0 wait state from 0

to 24 MHz and 1 wait state above 24 MHz)

● Prefetch is ON when the peripherals are enabled, otherwise it is OFF (to enable

prefetch the PRFTBE bit in the FLASH_ACR register must be set before clock setting

and bus prescaling)

● When the peripherals are enabled fPCLK = fHCLK

The parameters given in Table 20 to Table 26 are derived from tests performed under

ambient temperature and supply voltage conditions summarized in Table 15: General

operating conditions.
