Overview
The LC75844M 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 LC75844M can drive an LCD with up to 88 segments directly. The
LC75844M can also control up to 4 general-purpose output ports. Since the LC75844M 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.
Application
Car, Home frequency display
Features
Support for 1/4 duty 1/2 bias or 1/4 duty 1/3 bias drive of up to 88 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.
