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
measurement
scheme.
All Run-mode current consumption measurements given in this section are performed with a
reduced code that gives a consumption equivalent to Dhrystone 2.1 code.
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
All peripherals are disabled except when explicitly mentioned
The Flash memory access time is adjusted to the f
to 24 MHz, 1 wait state from 24 to 48 MHz and 2 wait states above)
Prefetch in ON (reminder: this bit must be set before clock setting and bus prescaling)
