—

*1 VDD is the highest pin and VSS5 the lowest for the bias voltage.

*2 Connect the specified capacitors to the voltage doubler and LCD bias generator.

*3 Make sure that the crystal oscillation frequency or the divided clock frequency falls within

this range.

Note 1: Ensure the chip is not exposed to any light.

Note 2: The bias voltage may exceed 5.5 V at some contrast stages. Adjust the stage with

software so that the bias voltage does not exceed 5.5 V.
