1 VDD = 3.3 V ± 10% / 5.0 V ± 10%, TA = 40 to 125 °C, unless otherwise specified.
2 All values need to be confirmed during device validation.
3 The min. and max variation across process voltage and temperature will be available after device characterization.
Expected to be within 10 mV.
4.9 Low voltage domain power consumption
Table 24 provides DC electrical characteristics for significant application modes. These values are indicative values; actual
consumption depends on the application.
