DC Electrical Characteristics
The below electrical characteristics are for proper CPU core and IO operation. For capacitive touchscreen electrical characteristics,
refer to the touchscreen user module data sheet.
DC Chip-Level Specifications
Table 8 lists the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V and -40°C
≤ T_A ≤ 85°C, 3.0V to 3.6V and -40°C ≤ T_A ≤ 85°C, or 2.7V to 3.0V and -40°C ≤ T_A ≤ 85°C, respectively. Typical parameters apply to
5V, 3.3V, or 2.7V at 25°C. These are for design guidance only.
