MOS INTEGRATED CIRCUIT
μ
PD16435, 16435A
DESCRIPTION
The
μ
PD16435 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
μ
PD16435 uses an external reference clock. The
μ
PD16435A 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)
