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 -40°C ≤ T ≤ 85°C, or 3.0V to 3.6V and -40°C ≤ T ≤ 85°C, respectively. Typical parameters apply to 5V and 3.3V at 25°C and

are for design guidance only or unless otherwise specified.
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.
