LC75843UGAGEVB
LC75843UGA LCD Driver IC
Evaluation Board
User'sManual
Overview
The LC75843UGAGEVB is an evaluation board for
operation check of 1/1 to 1/4 duty general-purpose LCD
driver IC (LC75843UGA). This evaluation board has
a power supply circuit, a controller circuit, an LCD driver IC
circuit, an LCD panel circuit, an LED circuit. Therefore, this
evaluation board can facilitate the operation check (state
setting and waveform monitor, etc.) of the LCD driver IC.
In addition, this evaluation board can automatically
demonstrate.
Features
• This Evaluation Board is Equipped with a Controller,
and the Control of the LCD Driver IC is Possible by
Serial Communication (CCB* Format)
• The 1/4 Duty LCD Panel is Implemented
• Capable of the LED Control by the General-purpose
Port of the LCD Driver IC (Capable of the LED
Brightness Adjustment by the PWM Control)
• Capable of Waveform Monitor of All Common
Outputs, All Segment Outputs and All General-purpose
Port Outputs
• This Evaluation Board can Separate the Signal between
Each Circuit Block. Therefore the External Input to an
LCD Driver IC is Possible
• This Evaluation Board has the Demonstration Mode
which Automatically Performs LCD Display and LED
Control by Controller Control
• This Evaluation Board is Pb-free and RoHS Compliant
