LC79431D

Dot Matrix LCD Driver

Overview

The LC79431D is a large-scale dot matrix LCD common

driver LSI. The LC79431D contains an 80-bit

bidirectional shift register and a 4-level LCD driver. The

input/output pins for cascade connection can be used to

further increase the bit count. The LC79431D can be

used in conjunction with segment driver LC79400D or

LC79401D (QFP100D) to drive a wide-screen LCD

panel.

Features

• On-chip LCD drive circuit (80 bits)

• Display duty of 1/64 to 1/256 selectable

• On-chip input/output pins support a further increase in

bit count

• Supports externally supplied bias voltage

• Operating supply voltage/operating temperature are:

VDD (logic block)

: 5 V ±10 % / –20 to +75 °C

VDD–VEE (LCD block) : 12 V to 32 V / –20 to +75°C

• CMOS process
