The LC75878W is 1/8 to 1/10 duty general-purpose LCD display driver used for character and graphics display. This product operates under the control of a microcontroller and can directly drive an LCD with up to 730 segments. It can also control up to 4 general-purpose output ports.

• 1/8duty1/4bias, 1/9duty1/4bias, and 1/10duty1/4bias drive schemes can be controlled from serial data.
• 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.
• Direct display of display data without the use of a decoder provides high generality.
• Built-in display contrast adjustment circuit.
• Up to 4 general-purpose output ports are included.
• Independent LCD driver block power supply VLCD.
• The INH pin is provided. This pin turns off the display and forces the general-purpose output ports to the low
• level.
• RC oscillator circuit
