HD66710

(Dot Matrix Liquid Crystal Display Controller/Driver)

Description

The HD66710 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 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 HD66710 is capable of displaying a single16-character line, two 16-character lines, or up to four

8-character lines.

The HD66710 software is upwardly compatible with the LCD-II (HD44780) which allows the user to

easily replace an LCD-II with an HD66710. In addition, the HD66710 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 HD66710 character generator ROM is

extended to generate 240 5 × 8 dot characters.

The low voltage version (2.7V) of the HD66710, combined with a low power mode, is suitable for any

portable battery-driven product requiring low power dissipation.
