UPD16435A
Overview
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.
- 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
