FEATURES
● Switching between 1/3 duty and 1/4 duty drive techniques under serial data control.● Switching between 1/2 bias and 1/3 bias drive techniques under serial data control.
● Up to 387 segments for 1/3 duty drive and 512 segments for 1/4 duty drive can be displayed.
● Switching between the segment, general-purpose, PWM, and clock output ports can be controlled using serial data (up to 8 general-purpose output ports, up to 3-channel PWM output ports, and one clock output port).
● Serial data input supports CCB format communication with the system controller.
● Serial data control of the power-saving mode based backup function and all the segments forced off function.
● Serial data control of the frame frequency for common and segment output waveforms.
● Serial data control of switching between the RC oscillator operating mode and external clock operating mode.
● High generality, since display data is displayed directly without decoder intervention.
● Built-in display contrast adjustment circuit
● Independent VLCD for the LCD driver block
● The INH pin can force the display to the off state.
