General Description
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.
