25.1 Function of temperature sensor
The on-chip temperature sensor measures and monitors the core temperature of the product, thus
ensuring the reliable operation of the product. The voltage output by the temperature sensor is proportional to
the core temperature, and there is a linear relationship between voltage and temperature. Its output voltage is
supplied to the ADC for conversion. FigureFigure25-1shows a block diagram of a temperature sensor.

25.2 Register for temperature sensor
25.2.1 Temperature sensor calibration data register TSN25
Address: 0x0050_066C
A read-only register that records calibration data for the temperature sensor1 is automatically loaded
when power is turned on or reset starts, and each chip has its own calibration data.
25.2.2 Temperature sensor calibration data register TSN85
Address: 0x0050_0668
A read-only register that records calibration data for temperature sensors2 is automatically loaded when
power is turned on or reset starts, with each chip having its own calibration data.
