6.3.5 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 V
DD
or V
SS
(no load)
● All peripherals are disabled except when explicitly mentioned
● The Flash memory access time is adjusted to the f
HCLK
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 f
PCLK
= f
HCLK
The parameters given in Ta bl e 2 0 to Tabl e 2 6 are derived from tests performed under
ambient temperature and supply voltage conditions summarized in Table 15: General
operating conditions.
