UPD16435A - DOT MATRIX LCD CONTROLLER/DRIVER

General 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.

Key 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 vol.

DATA SHEET µPD16435, 16435A DOT MATRIX LCD CONTROLLER/DRIVER 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). FEATURES • Can interface to 4 or 8-bit CPU. • Incorporates 119 segment outputs and 73 common outputs.
