LC75878W: LCD Driver, 1/8 to 1/10 Duty
The LC75878W is 1/8 to 1/10 duty general-purpose LCD display driver used for character and graphics display. This product operates under the control of a microcontroller and can directly drive an LCD with up to 730 segments. It can also control up to 4 general-purpose output ports.
Features- 1/8duty1/4bias, 1/9duty1/4bias, and 1/10duty1/4bias drive schemes can be controlled from serial data.
- 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.
- Direct display of display data without the use of a decoder provides high generality.
- Built-in display contrast adjustment circuit.
- Up to 4 general-purpose output ports are included.
- Independent LCD driver block power supply VLCD.
