33 / 64 page CY8C27143, CY8C27243 CY8C27443, CY8C27543 CY8C27643 Document Number: 38-12012 Rev. *X Page 33 of 64 DC POR and LVD Specifications Table 25 lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75 V to 5.25 V and –40 °C TA 85 °C, or 3.0 V to 3.6 V and –40 °C TA 85 °C, respectively. Typical parameters apply to 5 V and 3.3 V at 25 °C and are for design guidance only. Note The bits PORLEV and VM in the following table 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. Table 25.
