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 13: Current consumption
.
All Run-mode current consumption measurements given in this section are performed with a
reduced code that gives a consumption equivalent to 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 to the f
HCLK
frequency:
–
0 wait state and Prefetch OFF from 0 to 24 MHz
–
1 wait state and Prefetch ON above 24 MHz
When the peripherals are enabled f
PCLK
= f
HCLK
The parameters given in
are derived from tests performed
under ambient temperature and supply voltage conditions summarized in
