1. General Description
2. Feature
RAiO
The RA8803/RA8822 is a Dot-Matrix LCD controller which support both text and graphics mode. It built-in
two Display RAM for two layers display, and an embedded 512Kbyte character ROM that consists of
Chinese, English and ASCII fonts. In text mode, the RA8803/8822 support Chinese BIG5 code or GB code.
The system (MPU) does not need take a lot of time to show the Chinese font in graphics mode.
The RA8803/8822 support 8080/6800 like MPU interface, and also provide 4-Bitor 8-Bit data bus. For LCD
driver interface, it support the most of LCD Driver in the world. The RA8803 supports maximum resolution of
LCD panel is 320x240 dots, and RA8822 is 240x160 dots. If use extension mode then the RA8803 support
up to 640x240(320x480) dots resolution of Panel, and RA8822 support up to 480x160(240x320) dots. The
embedded 10-Bit ADC and Analog Switch provide the 4-wires Touch Panel interface. The 5-Bit DAC
provides the contrast control of the LCD panel. The RA8803/8822 also provide a 4x8 or 8x8 Key-Scan
interface that reduces the loading of MPU. Except for 16x16 Chinese font size, RA8803/8822 also provides
a great choice of different font sizes, such as 32x32, 48x48, or even 64x64. The embedded 512Byte SRAM
allows user build their own characters or symbols for convenience.
The RA8803/8822 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.
