DC POR and LVD Specifications
Table 20 lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V and -40°C
≤ T_A ≤ 85°C, or 3.0V to 3.6V and -40°C ≤ T_A ≤ 85°C, respectively. Typical parameters apply to 5V or 3.3V at 25°C. These are for design
guidance only.
Note The bits PORLEV and VM in the table below refer to bits in the VLT_CR register.
