G-TIMEElectronic Co., Ltd.

Segment-type 32x4 LCD Driver

ꢀ General Description

The GT9128A is a memory mapped segment-type LCD driver which has 128 patterns . It

can easily interface to microprocessor or microcontroller via a serial interface like accessing the

serial EEPROM. There are only three or four lines required for communication with the host

CPU.

ꢀ Features

1) Operates on 2.4V to 5.25V

2) Lower power CMOS process.

3) Compact package. ( 7.0x7.0 mm²square )

4) On chip built-in 256kHz oscillator

5) Serial EEPROM like access interface

6) Up to 4 common and 32 segment output.

7) Support 1/2,1/3, or 1/4 duty display.

8) Support 1/2 ,1/3 bias for LCD power display.

9) Programmable timer output for external control.

10) Selectable 2kHz or 4kHz base frequency output.

11) Power down mode to reduce power consumption.

ꢀ Applications

Portable sets, cameras, telephones, radio, VCD players, DVD players, MP3 players, digital

recorder, home appliance and those applications using LCD display.
