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 'computer control bus' 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
• Built in RC oscillator circuit
