CY8C24x23A Final Data Sheet
3. Electrical Specifications
3.3.8
DC POR, SMP, 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 ≤ TA ≤ 85°C, 3.0V to 3.6V and -40°C ≤ TA ≤ 85°C, or 2.4V to 3.0V and -40°C ≤ TA ≤ 85°C, respectively. Typical parameters
apply to 5V, 3.3V, and 2.7V 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.
