General questions on current consumption

[Rajneesh]

Hello Nordic team

I am working on nRF52832 dev board. SDK v-15.2.

My questions are following:

1) How much current consume if we use GPIOTE to register one pin interrupt?

2) How much current consume if we use ADC module?

3) How much current consume if we use fstorage to store custom data in internal memory?

4) How much current consume if we use I2c and SPI module?

Please let me know the current consumption rate for above mentioned four things.

Regards

Raj

1) The GPIOTE IN event consumes about 20 µA. The GPIOTE PORT event which can be used to register one pin interrupt and does not consume any extra current: https://infocenter.nordicsemi.com/topic/ps_nrf52840/gpiote.html?cp=3_0_0_5_9_1#concept_jyp_21x_lr

2) The active current of the SAADC is 1.24mA: https://infocenter.nordicsemi.com/topic/ps_nrf52840/_tmp/graviton/autodita/CURRENT/parameters.i_saadc.html?cp=3_0_0_4_1_0_6  The actual current consumption depends on how often you sample and for how long you sample.

3) Writing and erasing flash consumes about 3mA to 3.5mA, and how long it takes to write/erase is specified here: https://infocenter.nordicsemi.com/topic/ps_nrf52840/nvmc.html?cp=3_0_0_3_2_9#unique_797338916

4) SPI and I2C has a run current of 1.2mA.
