10. ELECTRICAL SPECIFICATIONS
Absolute Maximum Ratings (T
Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
Recommended Operating Range
Notes 1. V
Cautions 1. When using an external LCD driver, be sure to maintain these relations:
Logic system supply voltage
Booster supply voltage
Driver system supply voltage
Logic system input voltage
Driver system supply voltage
Maximum setting for LCD driver voltage
Logic system supply voltage
Booster supply voltage
Driver supply voltage
Driver reference supply input voltage
Logic system input voltage
Logic system output voltage
Logic system input/output voltage
Driver system input voltage
Driver system output voltage
Operating ambient temperature
Storage temperature
2. This item is the recommended parameter when the LCD has an external driver.
3. This item is the recommended parameter when an on-chip power supply circuit drives the LCD.
2. Maintain the relations shown in 8. POWER SUPPLY SEQUENCE when turning the power ON or OFF.
3. When using an external resister (when not using an on-chip resister for V
parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge
of suffering physical damage, and therefore the product must be used under conditions that ensure
that the absolute maximum ratings are not exceeded.
