Hi,

Sorry, we don't have any numbers for this. You can check out the datasheet for nRF52840,

http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52840.ps/_tmp/graviton/autodita/CURRENT/parameters.id_current_sleep.html?cp=2_0_0_4_1_0_0

The current variation wrt temperature will typically follow the same trend. Variation is typically within 4-7% for CPU and radio.

Hi Team,
Could you please let us know the worst case current consumption of nRF52832 at -40 and +85DegC.

Below are the current consumption values taken from datasheet: (we hope below are at room temp)
1)CPU current, running from flash, cache disabled, LDO : 8.0 mA
2)CPU current, running from flash, cache disabled, DCDC 3V : 3.9 mA
3)0 dBm TX @ 1 Mb/s Bluetooth Low Energy mode, Clock = HFXO : 7.1 mA
4)Radio RX @ 1 Mb/s Bluetooth Low Energy mode, Clock = HFXO : 6.5 mA
5)CPU running CoreMark from Flash, Radio 0 dBm TX @ 1 Mb/s, Bluetooth Low Energy mode, Clock = HFXO, Cache enabled : 9.2 mA
6)CPU running CoreMark from Flash, Radio RX @ 1 Mb/s, Bluetooth Low Energy mode, Clock = HFXO, Cache enabled : 9.2 mA

I will ask our test department for the numbers. I will give you an update soon.
