LC75847T Description
LC75847T CMOS LSI 1/3, 1/4 Duty General-Purpose LCD Driver .onsemi. Overview The LC75847T is 1/3 duty and 1/4 duty general-purpose LCD driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75847T can drive an LCD with up to 420 segments directly.
LC75847T 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 318 segments for 1/3 duty drive and 420 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
- Serial data control of frame frequency for mon and segment output waveforms
- High generality, since display data is displayed directly without decoder intervention
- Built-in display contrast adjustment circuit
- Independent VLCD for the LCD driver block
