DC Analog PSoC Block Specifications

Table 29 lists the 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.

DC POR, SMP, and LVD Specifications

Table 30 lists the 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 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.
