LC75897PW Overview
LC75897PW CMOS LSI 1/3, 1/4-Duty General-Purpose LCD Driver http://onsemi. Overview 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.
LC75897PW 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 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
- 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 the frame frequency for mon 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
