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
