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.
 RC oscillator circuit
