CMOS IC

LC75817NE, 75817NW

1/8 to 1/10 Duty Dot Matrix LCD Display Controllers/Drivers

with Key Input Function

Overview

The LC75817NE and LC75817NW are 1/8 to 1/10 duty dot

matrix LCD display controllers/drivers that support the

display of characters, numbers, and symbols. In addition to

generating dot matrix LCD drive signals based on data

transferred serially from a microcontroller, the LC75817NE

and LC75817NW also provide on-chip character display

ROM and RAM to allow display systems to be implemented

easily. These products also provide up to 4 general-purpose

output ports and incorporate a key scan circuit that accepts

input from up to 30 keys to reduce printed circuit board

wiring.

Features

• Key input function for up to 30 keys (A key scan is

performed only when a key is pressed.)

• Controls and drives a 5 × 7, 5 × 8, or 5 × 9 dot matrix LCD.

• Supports accessory display segment drive (up to 60

segments)

• Display technique: 1/8 duty 1/4 bias drive (5 × 7 dots)

1/9 duty 1/4 bias drive (5 × 8 dots)

1/10 duty 1/4 bias drive (5 × 9 dots)

• Display digits: 12 digits × 1 line (5 × 7 dots, 5 × 8 dots)

11 digits × 1 line (5 × 9 dots)

• Display control memory

CGROM: 240 characters (5 × 7, 5 × 8, or 5 × 9 dots)

CGRAM: 16 characters (5 × 7, 5 × 8, or 5 × 9 dots)

ADRAM: 12 × 5 bits

DCRAM: 48 × 8 bits

• Instruction function

Display on/off control

Display shift function

• Sleep mode can be used to reduce current drain.

• Built-in display contrast adjustment circuit

• Up to 4 general-purpose output ports are included.

• Serial data I/O supports CCB format communication

with the system controller.

• Independent LCD driver block power supply VLCD

• A voltage detection type reset circuit is provided to

initialize the IC and prevent incorrect display.

• The INH pin is provided. This pin turns off the display,

disables key scanning, and forces the general-purpose

output ports to the low level.

• RC oscillator circuit

• CCB is a trademark of SANYO ELECTRIC CO., LTD.

• CCB is SANYO’s original bus format and all the bus

addresses are controlled by SANYO.
