∗1 The potential difference between analog power supplies AVDD, AVss, the oscillation power supplies XVDD,
XVss and VDD, Vss should be within ±0.3V.
∗2 VLC1, VLC2, VLC3, VIN and VOUT should not exceed VDD + 0.3V.
Note) Usage exceeding absolute maximum ratings may permanently impair the LSI. Normal operation should
be conducted under the recommended conditions. Exceeding those conditions may adversely affect the
reliability of the LSI.

∗1 The optimal value depends on the characteristics of the used LCD element. Also, the LCD bias voltage is
biased to 1/3 the supply voltage by the resistor of approximately 20kΩ in the LSI.
