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 MCU is put 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
•
when the peripherals are enabled fPCLK = fHCLK
