Description
The HD66727, dot-matrix liquid crystal display controller and driver LSI incorporating a key scan function, displays alphanumerics, katakana, hiragana, and symbols. It can be configured to drive a dotmatrix liquid crystal display and control key scan functions under the control of an I2C bus or a clocksynchronized serial microprocessor. A single HD66727 is capable of displaying up to four 12-character lines, 40 segments, and 12 annunciators, and controlling up to a 4-by-8 key matrix, and driving three LED. The HD66727 incorporates all the functions required for driving a dot-matrix liquid crystal display such as display RAM, character generator, and liquid crystal drivers, and it also incorporates a booster for the LCD power supply and key scan functions.
