GENERAL DESCRIPTION
This chip is an LCD driver for a telephone dialer number display or other equipment. A maximum of
16 digits or 128 dots can be displayed, with 1/3 bias, 1/4 duty, and 32 segments.
In normal mode, a maximum of 128 dots (programmed by
P transceiver function) can be displayed
on the LCD panel. In clock mode, the LCD panel can display a built-in clock that can also be
programmed through the
P transceiver function. In timer mode, the LCD panel can display the
conversation time. The timer mode cannot be programmed by the
P.
A VDD1 pin is used in different voltage system applications to implement a voltage level shift function
to guarantee the transceiver data.
This chip is fabricated using Winbond's high performance CMOS technology.
