10.4.9 AC Programming Specifications

The following table lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V

and -40

°C ≤ T

≤ 85°C, or 3.0V to 3.6V and -40°C ≤ T

≤ 85°C, respectively. Typical parameters apply to 5V and 3.3V at 25°C and

are for design guidance only.
