●The LC75818PT is 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 LC75818PT also provide on-chip character display ROM and RAM to allow display systems to be implemented easily. These products also provide up to 4 general-purpose output ports and incorporate a key scan circuit that accepts input from up to 30 keys to reduce printed circuit board wiring.
