5.3.7

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
