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.

PQFP48 14x14 / QIP48E

[LC75833E]

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

SPQFP48 7x7 / SQFP48

[LC75833W]

 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

 Independent VLCD for the LCD driver block (VLCD can be set to any voltage

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

voltage.)

PQFP44 10x10 / QIP44M

[LC75833JE]

 The

pin can force the display to the off state

INH

 RC oscillator circuit

* Computer Control Bus (CCB) is an ON Semiconductor’s original bus format and

the bus addresses are controlled by ON Semiconductor.

The INH pin and Display Control

Since the LSI internal data (the display data and the control data) is undefined when power is first applied, applications

should set the INH pin low at the same time as power is applied to turn off the display (LC75833E, LC75833W: This

sets the S1/P1 to S8/P8, S9 to S35, and COM1 to COM3 to the V level. LC75833JE: This sets the S1/P1 to S8/P8, S9

SS

to S11, S13 to S22, S25 to S34, and COM1 to COM3 to the V level.) and during this period send serial data from the

SS

controller. The controller should then set the INH pin high after the data transfer has completed. This procedure prevents

meaningless displays at power on. (See Figure 3.)

Notes on the Power On/Off Sequences

Applications should observe the following sequence when turning the LC75833E, LC75833W, and LC75833JE power

on and off.

• At power on: Logic block power supply (V ) on → LCD driver block power supply (V

) on

DD

LCD

• At power off: LCD driver block power supply (V

) off → Logic block power supply (V ) off

DD

LCD

However, if the logic and LCD driver block use a shared power supply, then the power supplies can be turned on and off

at the same time.

Notes on Controller Transfer of Display Data

Since the LC75833E, LC75833W, and LC75833JE accept display data divided into three separate transfer operations,

we recommend that applications transfer all of the display data within a period of less than 30 ms to prevent observable

degradation of display quality.
