Difference between System ON sleep mode and System OFF sleep mode

[Somesh Burkule]

Hi Everyone,

I am confused in sleep modes of nrf52832.
Can you please tell me the difference between System ON sleep mode and System OFF sleep mode?

also the current consumption in both mode.

Hello, 

The nRF52832 Product Specification found in our Infocenter has all details.

System ON sleep mode

System OFF sleep mode

Electrical specs

Kind regards,

Hi Øyvind,

Thank you for your response.
Does that mean System ON constant latency and low power mode are sleep mode and System OFF sleep mode is deep sleep.

How is the Active mode is different than system ON mode? I can see in document Active mode current for nrf52832  with DCDC is 7mA and system ON current is 1.9mA.

Awaiting your reply.

Can you please link to where you find the Active mode current numbers? 

Yes, System ON is a sleep mode, with two sub modes constant latency and low power. When  System ON is enabled, only the LF-clock is running while sub mode constant latency will provide a higher current draw with more clocks running (not suitable for battery powered applications). System OFF will provide deep-sleep with no clock sources.

Kind regards,
Øyvind
