HD66730 Datasheet | Hitachi Semiconductor

Description The HD66730 is a dot-matrix liquid crystal display controller (LCD) and driver LSI that displays Japanese characters consisting of kanji, hiragana and katakana according to the Japanese Industrial Standard (JIS) Level-1 Kanji Set. The HD66730 incorporates the following five functions on a single chip: (1) display control function for the dot matrix LCD, (2) a display RAM to store character codes, (3) ROM fonts to support kanji, (4) liquid crystal driver, and (5) a booster to drive the LCD. A 2-line 6-character kanji display can easily be achieved by receiving character codes (2 bytes/ character) from the MPU. The font ROM includes 2,965 kanji from the JIS Level-1 Kanji Set, 524 JIS non-kanji characters, and 128 half-size alphanumeric characters and symbols. Full-size fonts such as Japanese kanji and half-size of fonts such as alphanumeric characters can be displayed together. In addition, display control equivalent to full bit mapping can be performed through horizontal and vertical dot-by-dot smooth scroll functions for each display line. To help make systems more pact, a three-line clock synchronous serial transfer method is adopted in addition to an 8-bit bus for interfacing with a microputer.
