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 <

< 85°C, or 3.15V to 3.5V and –40°C < T

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

are for design guidance only.
