Hitachi HD66720
The HD66720 dot-matrix liquid crystal display controller (LCD) and driver LSI incorporates a key-scan function and an LED display function, and displays alphanumeric character and symbols. A single HD66720 is capable of displaying a single 10-character line or two 8-character lines.DESCRIPTION
In addition, a single line of up to 40 characters can be displayed with extension drivers. Since the HD66720 incorporates a 5 × 6 matrix key scan circuit and two LED drive circuits, it can control front panels of telephone, car stereos, audio equipment, printers, or facsimiles with a single chip. A three-line clock synchronous serial transfer method is adopted for interfacing with a microcomputer, which greatly decreases the number of interface signals and makes it easy to miniaturize systems. This LSI is especially suitable for panels which can display five European languages (English, French, German, Italian, and Spanish), as used in new media products including car tuners for the radio data system (RDS), mini disc players (MD), and digital compact cassette players (DCC), personal handly phone, cellular phone.FEATURES
