10.3.9 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
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 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 Programmable System-on-Chip
Technical Reference Manual for more information on the VLT_CR register.
