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.
