There is an on-chip temperature sensor available on the analog input channel 10. The result of sampling the temperature sensor is translated to a temperature value by applying a transfer function, shown in Figure 8.
This transfer function has two key parameters that are used to calculate the Temperature in degrees Celsius, TCSENSOR and VSENSOR (see Equation 1).
The typical values for TCSENSOR and VSENSOR are specified in the section 12-bit ADC, Temperature Sensor and Built-In VMID of the data sheet. It is important to note that these values differ between the F543x and the F543xA, and this difference should be accounted for in the application.
