Electrical Characteristics Notes
1. All voltage values are referred to GND = 0V. If the LSI is used above these absolute maximum
ratings, it may become permanently damaged. Using the LSI within the following electrical
characteristic limits is strongly recommended for normal operation. If these electrical characteristic
conditions are also exceeded, the LSI will malfunction and cause poor reliability.
2. V_CC ≥ V5 must be maintained. In addition, if the SEG37/CL1, SEG38/CL2, SEG39/D, and SEG40/M
are used as extension driver interface signals (EXT = high), GND ≥ 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.
