TEMP — Temperature sensor

The temperature sensor peripheral (TEMP) measures die temperature over the temperature range of the device. Linearity compensation can be implemented if required by the application.

The main features of TEMP are the following:

Temperature range is greater than or equal to operating temperature of the device
Resolution is 0.25 degrees
TEMP analog electronics power down after temperature measurement is completed

To achieve the measurement accuracy stated in the electrical specification, the crystal oscillator must be selected as the HFCLK source, see CLOCK — Clock control for more information.

Operation

TEMP is started by triggering the START task.

When the temperature measurement is finished, a DATARDY event will be generated and the measurement result can be read from the TEMP register.

When the temperature measurement is finished, TEMP analog electronics power-down to save power.

TEMP only supports one-shot operation, meaning that every TEMP measurement has to be explicitly started using the START task.
