LC75818PT:1/8 to 1/10 Duty Dot-matrix LCD Controller/Driver with Key Input Function

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.

技术特性
  • Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)
  • Controls and drives a 5x7, 5x8, or 5x9 dot matrix LCD.
  • Supports accessory display segment drive (up to 80 segments)
  • Display technique
    : 1/8 duty 1/4 bias drive (5x7 dots)
    : 1/9 duty 1/4 bias drive (5x8 dots)
    : 1/10 duty 1/4 bias drive (5x9 dots)
  • Display digits: 16 digits1 line (5x7 dots, 5x8 dots, 5x9 dots)
  • Display control memory
    CGROM: 240 characters (5x7, 5x8, or 5x9 dots)
    CGRAM: 16 characters (5x7, 5x8, or 5x9 dots)
    ADRAM: 16x5 bits
    DCRAM: 64x8 bits
  • Instruction function
  • Sleep mode can be used to reduce current drain.
  • Built-in display contrast adjustment circuit
  • The frame frequency of the common and segment output waveforms can be controlled by instructions.
  • Serial data I/O supports CCB format communication with the system controller.
  • Independent LCD driver block power supply VLCD
  • A voltage detection type reset circuit is provided to initialize the IC and prevent incorrect display.
  • The INH pin is provided. This pin turns off the display, disables key scanning, and forces the general-purpose
    output ports to the low level.
  • RC oscillator circuit
