MOS INTEGRATED CIRCUIT
µPD16435, 16435A
DOT MATRIX LCD CONTROLLER/DRIVER
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).
FEATURES
• Can interface to 4 or 8-bit CPU.
• Incorporates 119 segment outputs and 73 common outputs.
(Display duty selectable from 1/35, 1/37, 1/71, 1/73)
• 5 × 7 character font 208 character data configuration character generation ROM and 16 character data configuration
character generation RAM, allowing composite full-dot and character display
• Incorporates extended display functions such as magnification, lateral scrolling, blink, reverse, etc.
• Operating voltage: 2.7 V to 5.5 V
• On-chip DC/DC converter: Selectable between ×4 set-up circuit and ×2 step-up circuit
• On-chip temperature correction circuit
• Master/slave operation capability
• On-chip power-on reset circuit
• On-chip oscillation circuit (µPD16435A)
• 232-pin TCP (Tape Carried Package)
