DC POR and LVD Specifications
The following table lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V
and 0°C < TA < 70°C, or 3.0V to 3.6V and 0°C < TA < 70°C, respectively. Typical parameters apply to 5V or 3.3V at 25°C and are for
design guidance only.
Note The bits PORLEV and VM in the table below refer to bits in the VLT_CR register. See the PSoC Mixed-Signal Array Technical
Reference Manual for more information on the VLT_CR register.
