LC75829PE, LC75829PW
1/4, 1/3-Duty General-Purpose
LCD Driver
Overview
The LC75829PE and LC75829PW are 1/4 duty and 1/3 duty general-
purpose microprocessor-controlled LCD drivers that can be used in
applications such as frequency display in products with electronic tuning.
In addition to being able to drive up to 208 segments directly, the
LC75829PE and LC75829PW can also control up to 4 general-purpose
output ports. Incorporation of an oscillation circuit helps to reduce the
number of external resistors and capacitors required.
Features
Support for 1/4-duty 1/3-bias or 1/3-duty 1/3-bias drive techniques under
serial data control.
When 1/4-duty: Capable of driving up to 208 segments
When 1/3-duty: Capable of driving up to 159 segments
Serial data input supports CCB* format communication with the system
controller. (Support 3.3 V and 5 V 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 function.
(Support for up to 4 general-purpose output ports)
Support for clock output function of 1ch.
Serial data control of the frame frequency of the common and segment
output waveforms.
Serial data control of switching between the internal oscillator operating
mode and external clock operating mode.
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.
Incorporation of an oscillator circuit.
(Incorporation of resistor and capacitor for an oscillation)
