    產(chǎn)品信息

    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.
    • 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
