1. General Description
2. Feature
RAiO
The RA8802/8820 is a Character/Graphic dot-matrix liquid crystal display controller (LCD) with embedded
512K Byte Font ROM. The RA8802 supports up to 320x240 LCD panel size and RA8820 supports up to
240x160. In tradition, users need a graphic LCM to display Chinese characters. Now Chinese character’s
display of RA8802/8820 presents a revolution. The RA8802/8820, instead of a MCU, can directly deal with
the access of Chinese/English fonts that consist of BIG5 or GB, and ASCII code.
The RA8802/8820 have some main functions as following. It’s equipped with 8-bit ADC, supporting touch
panel interface. DAC is 5-bit, providing the brightness control of the LCD panel. The RA8802/8820 built in
PLL/OSC two circuits provides user choice to generate system clock. The interface of RA8802/8820 fits both
of 8080/6800 series’ MCU and 4/8-bit data bus. Besides that, the interface of LCD driver is compatible with
many types of LCD drivers on the market.
Dot matrix liquid crystal display controller
supporting the display of Character/Graphic.
Fast Character/Graphical Mode for ASCII &
Chinese (Big5 Code and GB Code) support.
