power consumption

[MALI MAYUR]

hello everyone ...I am working on a project that uses the nRF52840 IC. I would like to implement a power-down mode to reduce power consumption. In my project, I am using BLE, ADC, RTC, and UART. Could you please let me know how many power-down options are available and suggest the best possible method for achieving low power consumption?

Hi,

If you haven't already, get yourself an Nordic PPK II that you can use to measures current consumption in real-time.

Normally a peripheral will only use current when active, e.g. actively receiving or transmitting. So depending on how often the application read or write to a peripheral it will use current during that period of time, if there is no specific activity, then it will run on RTC to maintain timing and ensure it can wakeup, during this idle period the current consumption should be 3uA.
