Overview

The LC75836W is 1/4-duty general-purpose microprocessor-controlled LCD driver that can be used in applications such as frequency display in products with electronic tuning. In addition to being able to drive up to 140 segments directly, the LC75836W can also control up to 4 general-purpose output ports.

Features

• 1/4 duty, 1/3 bias drive (Up to 140 segment can be displayed.)

• Serial data input supports CCB* format communication with the system controller (support 3V operation).

• Serial data control of the power-saving mode based backup function and the all segments forced off function.

• Serial data control of switching between the segment output port and general-purpose output port functions.

• Serial data control of the frame frequency of the common and segment output waveforms.

• Either RC oscillator operating or external clock operating mode can be selected with the serial control data.

• High generality, since display data is displayed directly without the intervention of a decoder circuit.

• The INH pin allows the display to be forced to the off state.

• RC oscillation circuit (with external resistor and capacitor)
