Uncalibrated Temperature Measurement

To perform an uncalibrated temperature measurement, with an accuracy of ±5 °C, follow this

procedure:

Set TSENS_CONTROL to 1 (power-up temperature sensor)

Wait for 100 µs

Set TSENS_CONTROL to 31

Wait for 10 µs

Set TSENS_CONTROL to 27

Wait for 1 µs

Set TSENS_CONTROL to 11

Wait for 1 µs

Set TSENS_CONTROL to 9

10.

Wait for 1 µs

11.

Set TSENS_CONTROL to 33

12.

Wait for 200 µs

13.

Read TSENS_REF and TSENS_CONV

14.

Calculate the uncalibrated temperature with the equation

Equation 17:

�� [°��] =

425 × ��_��

��_��

− 273.15

15.

To start a new measurement, go back to step 3

16.

To power down the temperature sensor, set TSENS_CONTROL to 0

Information

The temperature measurement uses the internal clock. This means that the sensor must

have followed the flow chart in section 7.4.3 until atleast the soft reset release step before a

temperature measurement can be started.

Calibrated Temperature Measurement

The accuracy of temperature measurements can be improved to ±1 °C after performing a

single-point calibration.

During wafer test, temperature is measured in a controlled environment. Calibration data is

written to the OTP memory of the sensor.

In section 7.8.5 we described how to read out data from OTP fuses.
