| 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.

Functional Description : Clock The CL1 is the clock to latch data on the falling edge. It latches the data input from the bidirectional shift register at the falling edge of CL1 and transfers its outputs to the LCD driver circuit. The CL2 is the clock to shift data on the falling edge. It shifts the serial data at the falling of CL2 and transfers the output of each bit of the register to the latch circuit. Shift Registers And Data I/O The GSM793E supplies two sets of 40-bit shift register, which controls the shift direction by SHL1 & SHL2. The SHL1 controls the 1st 40-bit shift register, and SHL2 controls the 2nd 40-bit shift register. When SHL1 is connected to VDD, the 1st shift direction is from S40 to S1; when SHL1 is connected to VSS, the shift direction changes from S1 to S40. When SHL2 is connected to VDD, the 2nd shift direction is from S80 to S41; when SHL2 is connected to VSS, the shift direction changes from S41 to S80. The DL1, DR1, DL2, DR2 are data input or output option function.
