Overview
The LC75810E and LC75810T are 1/8 to 1/10 duty dot matrix LCD display controllers/drivers that support 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 LC75810E and LC75810T also provide on-chip character display ROM and RAM to allow display systems to be implemented easily.
