LC75833E, LC75833W, LC75833JE

1/3 Duty General-Purpose LCD Driver

Overview

The LC75833E, LC75833W, and LC75833JE are 1/3-duty general-purpose

LCD display drivers that can be used for frequency display in electronic tuners

under the control of a microcontroller. The LC75833E and LC75833W can

drive an LCD with up to 105 segments directly, the LC75833JE can drive an

LCD with up to 93 segments directly. The LC75833E and LC75833W and

LC75833JE can also control up to 8 general-purpose output ports. Since the

LC75833E, LC75833W, and LC75833JE 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.

Features

 Supports both 1/3 duty 1/2 bias and 1/3 duty 1/3 bias LCD drive under serial

data control

LC75833E, LC75833W: up to 105 segments

LC75833JE: up to 93 segments

(without the S12, S23, S24, S35 segment output pins from the LC75833E,

LC75833W)

 Serial data input supports CCB* format communication 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

 High generality, since display data is displayed directly without decoder

intervention

in the range 2.7 to 6.0 volts, regardless of the logic block power-supply

voltage.)

 The INH pin can force the display to the off state

 RC oscillator circuit
