NRF52810 Operating Temperature

Yes, the maximum temperatures are specified for the ambient temperature, and not what the internal temperature sensor will show, as this will get more inaccurate at extreme high and low temperatures. The nRF52810 will work as expected in ambient temperatures of -40 to +85°C.

Hi Simon,

Thanks a lot for your answer.

We performed some tests in the environmental chamber with an ambient temperature set to 70°C. In this condition, the die temperature detected from the internal nRF52810 temperature sensor was approx. 80°C.

After this test I can more precisely ask you the following question:

Can I reliably operate the nRF52810 at an ambient temperature of 85°C (that will cause its die temperature to rise to approx. 95°C)?

Thanks a lot and kind regards,

Nele

Hi Nele

1. The operating temperature is the ambient temperature in which the nRF52810 is tested to work as intended. So it is tested to work in environments that are from -40 to +85°C.

2. The best way to test it would be to have a cold/heat chamber where you can set the temperature yourself to test the SoC in the minimum and maximum.

3. The max would be +85°C. If it gets any higher than this we can't guarantee the nRF52810 operates as intended, as it has only been tested/characterized up to 85 degrees.

4. The risks include the component being damage, the SoC operating in an undefined state, reduced lifespan, increased current consumption, lower clock accuracy resulting in worse radio performance.
