Product Overview
产品说明
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.
特性
 
  • Key input function for up to 35 keys (A key scan is performed only when a key is pressed.)
  • Controls and drives a 5x7 or 5x8 dot matrix LCD.
  • Supports accessory display segment drive (up to 65 segments)
  • Display technique:
    1/8 duty 1/4 bias drive (5x7 dots)
    1/9 duty 1/4 bias drive (5x8 dots)
  • Display digits: 13 digits1 line (5x7 dots), 12 digits1 line (5x8 dots)
  • Display control memory
    CGROM: 240 characters (5x7 or 5x8 dots)
    CGRAM: 16 characters (5x7 or 5x8 dots)
    ADRAM: 13x5 bits
    DCRAM: 52x8 bits
  • Instruction function
  • Sleep mode can be used to reduce current drain.
  • Built-in display contrast adjustment circuit
  • Switching between key scan output and general-purpose output ports can be controlled with instructions.
  • PWM output for adjusting the LED backlight brightness
  • The frame frequency of the common and segment output waveforms can be controlled by instructions.
  • Serial data control of switching between the RC oscillator operating mode and external clock operating mode.
  • 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
