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. It 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.
