Dot Matrix LCD Driver

Overview

The LC79430D is a large-scale dot matrix LCD common

driver LSI. The LC79430D contains an 80-bit

bidirectional shift register and is equipped with a 4-level

LCD driver. The input/output pins for cascade connection

can be used to further increase the IC’s number of bits.

The LC79430D can be used in conjumction with segment

driver LC79400D, LC79401D (QFP100D) to drive a

wide-screen LCD panel.

Functions and Features

• On-chip LCD drive circuit (80 bits)

• Display duty selection ranging from 1/64 to 1/256

• On-chip input/output pins support further increases in

bit number

• Supports externally supplied bias voltage

• On-chip 80-bit bidirectional shift register (supports 40-

bit × 2 division)

• Supports single mode (80-bit shift register) and dual

mode (40-bit × 2 shift register) applications

(1) O1 → O80

(2) O80 → O1

Single mode

(3) O1 → O40 and O41 → O80 Single mode

(4) O80 → O41 and O40 → O1

All four of the shift direction selection listed above all

supported.
