The LC75814V is a 1/4 duty general-purpose LCD driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75814V can drive an LCD with up to 64 segments directly. The LC75814V can also control up to 4 general-purpose output ports. Since the LC75814V uses 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.
