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 controller/driver. A single HD66712 is capable of displaying a single 24-character line, two 24-character lines, or four 12-character lines.
