CC2340R5: about temperature sensor

Jerry Kuo

Part Number: CC2340R5

Hi team,

My customer is development CC2340R5 SW and need temperature monitor feature. Please help clarify below items. Thank you.

Which API should we utilized to obtain the ADC value?
What is the range and accuracy of the ADC (e.g., 12-bit)?
Are these features done by the temperature sensor (inside CC2340R5) or is there any other element that is also in use?

I would recommend they use the temperature drivers. A good example for them to run would be the temperatureNotify example in the SDK.

These elements are done with the internal temperature sensor.

Kind Regards,

Hi Rogelio,

Thank you. How about the range and accuracy of the ADC (e.g., 12-bit)?

Hi Rogerlio,

or how about the accuracy of the temperature result ? Should customer do any calibration process to improve the accuracy ?

Hi Jerry,

From the code snippet above it seems as though the temperature is saved in a 32 bit register. In Regards to accuracy that can be found in the data sheet

Kind Regards,

Rogelio
