52833 uart power consumption

[William.wei]

hi support team,

i found that 52833 UART power is different from 832,

in SDK17.0.2,

832 is still 1.15 mA(with DMA), however 833 is about 0.437 mA(with DMA),

832 is still 0.300 mA(without DMA), however 833 is about 0.320 mA(without DMA),

just confirm that my testing is right.

i used NUS as example.

Regards,

William.

Hi, your measurements are in line with what I'm measuring here as well.

This is my result:

	nRF52832	nRF52833
DMA	1.18 mA	0.44 mA
no DMA	0.27 mA	0.30 mA

There will always be a little chip to chip variation, so you will never measure exactly the same on two different samples.

Thank you!

The performance is great in 833!
