LC75897PW:1/4, 1/3 Duty General Purpose LCD Driver
The LC75897PW is 1/3 duty and 1/4 duty general-purpose LCD display driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75897PW can drive an LCD with up to 512 segments directly. The LC75897PW can also control up to 8 general-purpose output ports. The LC75897PW has a built-in of up to three PWM output port channels, which enables to adjust the brightness of the RGB LED backlight.
技术特性
- 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.
- RC oscillator circuit
