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
• 5 × 8 dot matrix possible
• Clock-synchronized serial interface capability; can interface with 4- or 8-bit MPU
• Low-power operation support:
2.7 to 5.5V (low voltage)
Wide liquid-crystal voltage range: 2.7 to 11.0V max.
• Booster for liquid crystal voltage
Two/three times (13V max.)
• High-speed MPU bus interface
(2MHz at 5-V operation)
