LC75814V-MPB-E

Overview
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.
Features● Support for 1/4 duty 1/2 bias or 1/4 duty 1/3 bias drive of up to 64 segments 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.● RC oscillator circuit
