An on-board thermal IC (Texas Instruments TMP421) connected to the I²C0 interface can work as a local temperature sensor, providing the measurement of its internal temperature, but also as a remote temperature sensor, since it is connected to the XADC_DXP/XADC_DXN of the Zynq processor, providing the measurement of the Zynq internal temperature.

For a detailed description of the thermal IC characteristics, please refer to the TMP421 datasheet.
