    產(chǎn)品信息

    The LC75806PT is 1/4 duty and 1/3 duty LCD display driver that can directly drive up to 304 segments and can control up to 9 general-purpose output ports. This product also incorporates 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.)
    • 1/4 duty 1/3 bias and 1/3 duty 1/3 bias drive schemes can be controlled from serial data.
    • Capable of driving up to 304 segments using 1/4 duty and up to 231 segments using 1/3 duty.
    • Switching between key scan output and segment output can be controlled from serial data.
    • The key scan operation enabled/disabled state can be controlled from serial data.
    • Switching between segment output port and general-purpose output port can be controlled from serial data.
    • Switching between general-purpose output port, clock output port, and segment output port can be controlled from serial data.
    • (Up to 9 general-purpose output ports and up to one clock output port)
    • Serial data I/O supports 'computer control bus' format communication with the system controller. (Support 3.3 V and 5 V operation)
    • Sleep mode and all segments off functions that are controlled from serial data.
    • The frame frequency of the common and segment output waveforms can be controlled from serial data.
    • Switching between RC oscillator operating mode and external clock operationg mode can be controlled from serial data.
    • Direct display of display data without the use of a decoder provides high generality.
    • Built-in display contrast adjustment circuit.
    • Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.
    • RES pin provided for forcibly initializing the IC internal circuits.
