    產(chǎn)品信息

    The LC75857W is a 1/3 duty and 1/4 duty LCD display driver that can directly drive up to 164 segments and can control up to four general-purpose output ports. This product also incorporate a key scan circuit that accepts input from up to 30 keys to reduce printed circuit board wiring.
    • Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)
    • 1/3 duty and 1/4 duty drive schemes can be controlled from serial data.
    • 1/2 bias and 1/3 bias drive schemes can be controlled from serial data.
    • Capable of driving up to 126 segments using 1/3 duty and up to 164 segments using 1/4 duty.
    • Sleep mode and all segments off functions that are controlled from serial data.
    • Switching between key scan output and segment output can be controlled from the serial data.
    • The key scan operation enabled/disabled state can be controlled from the serial data.
    • Switching between segment output port and general-purpose output port can be controlled from serial data.
    • The common and segment output waveform frame frequency can be controlled from the serial data.
    • Switching between RC oscillator mode and external clock mode can be controlled from the serial data.
    • Serial data I/O supports 'computer control bus' format communication with the system controller.
    • Direct display of display data without the use of a decoder provides high generality.
    • Independent VLCD for the LCD driver block.
    • Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.
