LC75813E Overview
The LC75813E and LC75813T can drive an LCD with up to 344 segments directly. The LC75813E and LC75813T can also control up to 8 general-purpose output ports. Since the LC75813E and LC75813T use separate power supply systems for the LCD drive block and the logic block, the LCD driver block power-supply voltage can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage.
LC75813E Key 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 261 segments for 1/3 duty drive and 344 segments for 1/4 duty drive can be displayed
- Serial data input supports CCB format munication 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 switching between the segment output port and the general-purpose output port functions
LC75813E Applications
- Serial data control of frame frequency for mon and segment output waveforms
