LC75813E Overview
EN7159 LC75813E, LC75813T CMOS LSI 1/3, 1/4 Duty General-Purpose LCD Driver http://onsemi. Overview The LC75813E and LC75813T are 1/3 duty and 1/4 duty general-purpose LCD drivers that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75813E and LC75813T can drive an LCD with up to 344 segments directly.
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
- Serial data control of frame frequency for mon and segment output waveforms
- High generality, since display data is displayed directly without decoder intervention
- Independent VLCD for the LCD driver block (VLCD can be set to any voltage in the range 2.7 to 6.0 volts, regardless
- The INH pin can force the display to the off state
