LC450029PKB

1/4 and 1/3-Duty General-Purpose

LCD Driver

www.onsemi.com

Overview

The LC450029PKB is 1/4 duty and 1/3 duty general-purpose microcontroller-

controlled LCD drivers that can be used in applications such as frequency

display in products with electronic tuning. In addition to being capable to drive

up to 208 segments directly. The internal oscillation circuit helps to reduce the

number of external resistors and capacitors required. The chip shape is slim for

COG (Chip-On-Glass) implementation. The operating temperature range is

from 40C to +105C

Application

 Car or general consumer electronic LCD display equipment.

Features

 Selectable 1/4-duty or 1/3-duty drive by the serial control data

When 1/4-duty: Capable of driving up to 208 segments

When 1/3-duty: Capable of driving up to 159 segments

 1/3-bias only

 Serial data input supports CCB* format communication with the system

controller. (For 5 V operation only)

 The power-saving mode is selectable by the serial control data, and supports

low power consumption.

 Adjustable the frame frequency of the common and segment output waveforms

by the serial control data

 Selectable the internal oscillator operating or external clock operating mode by

the serial control data

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

intervention of a decoder circuit.

 The

pad allows all LCD segments to be forced to the off state.

INH

 With a built-in oscillator circuit

(External resistors and capacitors are unnecessary.)

 The stability of the LCD bias voltage is high by a built-in LCD bias generator

with voltage-follower buffers.

 Shipping form: Chip with Au bumps in tray.

 Allowable operating voltage (V , V I)

: +4.5 V to +6.0 V

DD DD

 Allowable wide operating temperature ranges

: 40C to +105C

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

the bus addresses are controlled by ON Semiconductor.
