which soc is best suitable for low power

[Bimal]

Which has different best low power mode among other SoCs. Can anyone let us know the comparison of it?

• whether to go for nRF51822 or nRF52832

Hi

Generally speaking about current consumption of nRF51 vs nRF52: Most peripherals of the nRF52 are about 2x as efficient as on the nRF51, i.e. the nRF52 peripherals draw generally ~50% of the current compared to the nRF51 peripherals. Sleep current of nRF52 is also about 50% compared to nRF51. The largest exception is the nRF52 CPU which is generally 4x-10x as sufficient as the nRF51 CPU.

Hi

I looked for the datasheet of nRF52832 but was not able to find it on website. Can you share me the datasheet of nRF52832.

Yes, it is on our infocenter
