AC SPI Specifications
Table 31 and Table 32 list 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 apply to 5 V, 3.3 V, or 2.7 V at 25 °C. These are for design guidance only.
