General Description
RA8806 is a LCD controller for Dot-Matrix type STN-LCD which supports both character and graphic mode display. The RA8806 has built-in two Display Data RAM(DDRAM) for two layers display, and has an embedded font ROM which is capable of displaying the full-size(16x16 pixels) traditional Chinese font(BIG5, 13973 characters) or simplified Chinese font(GB, 9216 characters). RA8806 also contains 4x256 embedded half-size (8x16 pixels) characters that can display ISO8859-1 ~ 4(or called Latin-1 ~ 4) alphabets using at most of English speaking and Europe countries.
