LCD controller maps out many languages
A RAiO Technology product story
Edited by the Electronicstalk editorial team Dec 18, 2007
The RA8816 is a dot-matrix LCD driver that supports both character and graphics modes.
RAiO Technology has developed an LCD controller driver IC that is capable of displaying traditional and simplified Chinese, English, ASCII, Hiragana, Katagana, Latin ext A and Latin ext B characters.
The RA8816 is a dot-matrix LCD driver that supports both character and graphics modes.
It has a built-in 256Kbyte character ROM that stores dot patterns of Chinese, English and ASCII fonts.
The embedded 1170byte display RAM supports LCD panels up to 144 x 65 dots.
The RA8816 also provides a buffer memory for scrolling functions.
It supports up, down, left and right scrolling features, and all scrolling is executed by hardware.
In character mode, the RA8816 supports Chinese BIG5 code or GB code with no need for conventional external CG ROM, therefore the system (MPU) software processing time can be reduced dramatically for displaying Chinese fonts in graphics mode.
It also provides small ASCII (8x8) and big ASCII (8x16) fonts for English characters, Japanese, European and Latin.
The RA8816 also integrates several powerful functions that including contrast adjustment, 4x5 key-scan, eight general purpose I/Os and EL backlight signal for an EL driver.
The RA8816 is a highly integrated chip in a gold bump die format that allows chip-on-glass mounting.
The device is sampling now, and RAiO Technology can provide design-in support to customers.
