LC79430KNE

Overview

The LC79430KNE is a large-scale dot matrix LCD common driver LSI. The LC79430KNE 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 LC79430KNE can be used in conjunction with segment driver

LC79401KNE (QIP100E) to drive a wide-screen LCD panel.

Features

• On-chip LCD drive circuit (80 bits)

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

• On-chip input/output pins support a 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

• Operating power supply voltage/operating temperature include

• CMOS process

• 100-pin flat plastic package (QIP100E)
