■ ELECTRICAL CHARACTERISTICS
1. Absolute Maximum Ratings
(VSS = 0.0 V)
*1: Use AVCC and VCC set at the same voltage.
Take care so that AVCC does not exceed VCC, such as when power is turned on.
*2: VCC must not exceed V3. Unless LCD is used, the same setting must be executed.
Precautions: Permanent device damage may occur if the above “Absolute Maximum Ratings” are exceeded. Func-
tional 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.
