Ordering number : ENA1417B LC75812PT CMOS IC 1/8, 1/9 Duty Dot Matrix LCD Display Controllers/Drivers with Key Input Function http://onsemi.com Overview The LC75812PT is 1/8, 1/9 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 LC75812PT also provide on-chip character display ROM and RAM to allow display systems to be implemented easily. These products also provide up to 3 general-purpose output ports and incorporate a key scan circuit that accepts input from up to 35 keys to reduce printed circuit board wiring. Features • Key input function for up to 35 keys (A key scan is performed only when a key is pressed.
