LC75811E, 75811W
1/8 to 1/10 Duty Dot Matrix LCD Display Controller/Driver
Overview
The LC75811E and LC75811W are 1/8 to 1/10 duty dot
matrix LCD display controller/drivers that supports the
display of characters, numbers, and symbols. In addition to
generating dot matrix LCD drive signals based on data
transferred serially from a microcontroller, the LC75811E
and LC75811W also provide on-chip character display ROM
and RAM to allow display systems to be implemented easily.
