The device can maintain a safe junction temperature below the recommended maximum value of 125°C even when operated on a PCB with a maximum board temperature (TPCB) of 105 °C. This can shown by the following example calculation, which assumes the total device power (PTOTAL) computed with all blocks enabled using the typical current consumption from the Electrical Characteristics (VDD = 3.3 V, VDDO = 1.8 V) and the thermal data in Thermal Information: 10-Layer Custom PCB with no airflow.
