Overview
The LC75838E and LC75838W are 1/8 to 1/10 duty general-purpose LCD display drivers used for character and graphics display. These products operate under the control of a microcontroller and can directly drive an LCD with up to 380 segments. They can also control up to 3 general-purpose output ports.

Features
• 1/8duty–1/4bias, 1/9duty–1/4bias, and 1/10duty–1/4bias
   drive schemes can be controlled from serial data.
   1/8duty–1/4bias: up to 320 segments
   1/9duty–1/4bias: up to 351 segments
   1/10duty–1/4bias: up to 380 segments
• 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.
• Direct display of display data without the use of a
   decoder provides high generality.
• Built-in display contrast adjustment circuit.
• Up to 3 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
