DC POR, SMP, and LVD Specifications
Tab le 24 lists the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75 V to 5.25 V and
–40 °C  T
A
 85 °C, 3.0 V to 3.6 V and –40 °C  T
A
 85 °C, or 2.4 V to 3.0 V and –40 °C  T
A
 85 °C, respectively. Typical parameters
are measured at 5 V, 3.3 V, and 2.7 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 Sytem-on-Chip
Technical Reference Manual for more information on the VLT_CR register.
