54 / 127 page  Electrical Characteristics STA108x, STA109x 54/127 DS13319 Rev 2 4.3 Absolute Maximum Ratings This product contains devices to protect the inputs against damage due to high static voltages, however it is advisable to take normal precautions to avoid application of any voltage higher than the specified maximum rated voltages. Table 18 lists the absolute maximum rating for the Accordo2 families of processors. Table 18. Voltage Characteristics Symbol Parameter Limit Values Unit Min Max VDD_IO_ON SR Power Supply pins for the IO buffers of the always ON section VGND - 0.3 VGND + 3.90 V VDD_IO SR Power Supply pins for the IO buffer in switchable domain. VGND - 0.3 VGND + 3.90 V VDD SR Power Supply pins for the Internal logic of switchable domain VGND - 0.3 VGND + 1.50 V ADC2_AVDD SR Analog Power supply for SAR ADC VADC2_GND - 0.3 VADC2_AGND + 3.90 V ADC2_VREFP SR Positive reference voltage for SAR ADC VADC2_GND - 0.3 VADC2_AGND + 3.90 V DAC_AVDD SR Analog Voltage supply for DAC.
