It supports up, down, left and right scrolling features, and all of the scrolling are execute by hardware. In character mode, the RA8816 supports Chinese BIG5 code or GB code. The system(MPU) does not need take a lot of time to show the Chinese font in graphic mode. It also provides small ASCII(8x8) and big ASCII(8x16) font for English character, Japanese, European and Latin. The RA8816 integrates many powerful hardware that including Contrast adjustment, 4x5 Key-Scan, eight General Purpose I/O and EL Backlight signals for EL driver. The RA8816 is a high integration chip of LCD Controller. It reduce a lot of time for system develop, and save much cost for hardware system that due to it provides many features for related LCD display application. 2.
