HD66712 (LCD-II/F12)

(Dot-Matrix Liquid Crystal Display Controller/Driver)

Description

The HD66712 dot-matrix liquid crystal display

controller and driver LSI displays alphanumerics,

numbers, and symbols. It can be configured to

drive a dot-matrix liquid crystal display under the

control of a serial or a 4- or 8-bit microprocessor.

Since all the functions such as display RAM,

character generator, and liquid crystal driver,

required for driving a dot-matrix liquid crystal

display are internally provided on one chip, a

minimum system can be interfaced with this con-

troller/driver.

A single HD66712 is capable of displaying a single

24-character line, two 24-character lines, or four

12-character lines.

The HD66712 software is upwardly compatible

with the LCDII (HD44780) which allows the user

to easily replace an LCD-II with an HD66712. In

addition, the HD66712 is equipped with functions

such as segment displays for icon marks, a 4-line

display mode, and a horizontal smooth scroll, and

thus supports various display forms. This achieves

various display forms. The HD66712 character

generator ROM is extended to generate 240 5

dot characters.

The low-voltage operation (2.7 V) of the HD66712,

combined with a low-power mode, is suitable for

any portable battery-driven product requiring low

power consumption.

• Low-power operation support:

— 2.7 to 5.5 V (low voltage)

— Wide liquid-crystal voltage range: 3.0 to

13.0 V max.

• Booster for liquid crystal voltage

— Two/three times (13 V max.)

• High-speed MPU bus interface

(2MHz at 5-V operation)

• Extension driver interface

• Character display and independent 60-icon mark

display possible

• Horizontal smooth scroll by 6-dot font width

display possible

• 80

8-bit display RAM (80 characters max.)

• 9,600-bit character generator ROM

— 240 characters (5

8 dot)

• 64

8-bit character generator RAM

— 8 characters (5

8 dot)

• 16

8-bit segment icon mark

— 96-segment icon mark

• 34-common

60-segment liquid crystal display

driver

• Programmable duty cycle

(See list 1)

• Software upwardly compatible with HD44780

• Wide range of instruction functions:

— Functions compatible with LCD-II: Display

clear, cursor home, display on/off, cursor

on/off, display character blink, cursor shift,

display shift

— Additional functions: Icon mark control, 4-

line display, horizontal smooth scroll, 6-dot

character width control, white-black invert-

ing blinking cursor

• Automatic reset circuit that initializes the con-

troller/driver after power on (standard version

only)

Features

• 5

8 dot matrix possible

• Clock-synchronized serial interface capability; can

interface with 4- or 8-bit MPU
