Overview
The LC75813E and LC75813T are 1/3 duty and 1/4 duty general-purpose LCD drivers that can be used for
frequency display in electronic tuners under the control of a microcontroller. The LC75813E and LC75813T can
drive an LCD with up to 344 segments directly. The LC75813E and LC75813T can also control up to 8 general-
purpose output ports. Since the LC75813E and LC75813T use separate power supply systems for the LCD drive
block and the logic block, the LCD driver block power-supply voltage can be set to any voltage in the range 2.7 to
6.0 volts, regardless of the logic block power-supply voltage.
Features
Switching between 1/3 duty and 1/4 duty drive techniques under serial data control.
Switching between 1/2 bias and 1/3 bias drive techniques under serial data control.
Up to 261 segments for 1/3 duty drive and 344 segments for 1/4 duty drive can be displayed.
Serial data input supports CCB format communication with the system controller.
Serial data control of the power-saving mode based backup function and all the segments forced off function.
Serial data control of switching between the segment output port and the general-purpose output port functions.
Serial data control of frame frequency for common and segment output waveforms.
High generality, since display data is displayed directly without decoder intervention.
Independent VLCD for the LCD driver block (VLCD can be set to any voltage in the range 2.7 to 6.0 volts, regardless
of the logic block power-supply voltage.)
The INH pin can force the display to the off state.
