HD66730/HD66731
(Dot-Matrix Liquid Crystal Display Controller/Driver Supporting
Japanese Kanji, Korean Font Display)
Description
The HD66730/1 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 HD66730/1 incorporates the following five functions on a single
chip: (i) display control function for the dot matrix LCD, (ii) a display RAM to store character codes, (iii)
ROM fonts to support kanji, (iv) liquid crystal driver, and (v) a booster to drive the LCD. A two 6-character
(HD66730) or four 10-character (HD66731) 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 compact, a three-line
clock synchronous serial transfer method is adopted in addition to an 8-bit bus for interfacing with a
microcomputer.
