DATA SHEET

MOS INTEGRATED CIRCUIT

DESCRIPTION

The

µPD16435 and 16435A are controllers/drivers for a 119 × 73-dot LCD, and perform LCD full-dot and character

composite display by means of control by a microprocessor that has a 4 or 8-bit data bus. A charge pump type

DC/DC converter is also incorporated, enabling 3 or 5 V single power supply drive.

The

µPD16435 uses an external reference clock. The µPD16435A has the on-chip oscillation circuit (external

crystal resonator).
