Electrical Characteristics Notes
1. All voltage values are referred to GND = 0V. If the LSI is used above the absolute maximum ratings,
it may become permanently damaged. Using the LSI within the following electrical characteristic is
strongly recommended to ensure normal operation. If these electrical characteristic are also exceeded,
the LSI may malfunction or exhibit poor reliability.
2. V_CC ≥ V1 ≥ V2 ≥ V3 ≥ V4 ≥ V5 must be maintained.
3. For die products, specified up to 75°C.
4. For die products, specified by the die shipment specification.
5. The following four circuits are I/O pin configurations except for liquid crystal display output.
