LC75810E
CMOS IC
1/8 to 1/10 Duty Dot Matrix LCD
LC75810T _{Display Controllers/Drivers}
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.
