The LC75833E is a 1/3-duty general-purpose LCD display driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75833E can drive an LCD with up to 105 segments directly. The LC75833E can also control up to 8 general-purpose output ports. Since the LC75833E 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.

Supports both 1/3 duty 1/2 bias and 1/3 duty 1/3 bias LCD drive under serial data control
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
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
