Revision A4
GENERAL DESCRIPTION
This chip is a LCD driver for a telephone dialer number display or other equipment. A maximum of 20
digits or 160 dots can be displayed, with 1/3 bias, 1/4 duty, and 40 segments.
In normal mode, there are max. 160 dots (can be programmed by
P) can be displayed on the LCD
panel. In clock mode, the LCD panel can display a built-in clock that can be read out by
P.
A VDD1 pin is used in different voltage system application to implement voltage level shift
function so the transceiver data can be guaranteed.
This chip is fabricated using Winbond's high performance CMOS technology.
