Cypress CY8C22113, CY8C22213 manual DC POR and LVD Specifications

CY8C22x13 Final Data Sheet 3. Electrical Specifications

3.3.7DC 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 ≤ TA ≤ 85°C, or 3.0V to 3.6V and -40°C ≤ TA ≤ 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.
