1/8 to 1/10 Duty General-Purpose LCD Display Drivers
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 V_LCD.
• 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
