(Continued)

(VSS = 0.0 V)

Precautions: Permanent device damage may occur if the above “Absolute Maximum Ratings” are exceeded.

Functional operation should be restricted to the conditions as detailed in the operational sections of

this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect

device reliability.

2. Recommended Operating Conditions

(VSS = 0.0 V)

*1: The minimum operating power supply voltage varies with the operating frequency and execution time (instruction

cycle).

*2: The liquid-crystal power supply range and optimum value vary depending on the characteristics of the liquid-

crystal display element used.
