MOS INTEGRATED CIRCUIT
µPD16435, 16435A
DOT MATRIX LCD CONTROLLER/DRIVER
DESCRIPTION
The µPD16435 and 16435A are controllers/drivers for a 119 à 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 à 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 Ã4 set-up circuit and Ã2 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)
