GSM793E

GSM793E Syntek Semiconductor Co., Ltd. (80CH Segment Driver For Dot Matrix LCD) Introduction : GSM793E is a segment driver for dot matrix type LCD display. It features 80 channels with 40 X 2 bits bi-directional shift registers, data latches, LCD drivers and logic control circuits. It is fabricated by high voltage CMOS process with low current consumption. The GSM793E can convert serial data received from an LCD controller, such as GSM7980, into parallel data and send out LCD driving waveforms to the LCD panel. The GSM793E is designed for general purpose LCD drivers. It can drive both static and dynamic drive LCD. The LSI can be used as segment driver. The GSM793E has pin function compatibility with the KS0063(B) that allows the user to easily replace it with an GSM793E. www.DataSheet4U.com Functions : l Dot matrix LCD driver with two 40 channel outputs l Bias voltage (V1 ~ V4) l input/output signals n n Input : Serial display data and control pulse from controller IC Output : 40 X 2 channels waveform for LCD driving Features : l Display driving bias : static to 1/5 l Power supply for logic : 2.7V ~ 5.5V l Power supply for LCD voltage (VDD~VEE) : 3V ~ 11V 100 Pin QFP package and bare chip available LCD Controller /Driver 1 /10 V1.1 GSM793E Syntek Semiconductor Co., Ltd.
