Dot-Matrix Liquid Crystal Display Controller/Driver

Hitachi -> Renesas Electronics 

HD66712U

(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 controller/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 × 8 dot characters.

The low-voltage operation (2.7V) of the HD66712, combined with a low-power mode, is suitable for any

portable battery-driven product requiring low power consumption.

Features
