RAiO RA6963 Dot Matrix LCD Controller Specification Version 1.4 July 07, 2009 RAiO Technology Inc. ©Copyright RAiO Technology Inc. 2007, 2008, 2009 RAiO TECHNOLOGY INC. 1/6 www.raio.com.tw RA6963 Preliminary Version 1.4 Dot Matrix LCD Controller 1. Overview The RA6963 is a dot matrix LCD Controller which fully compatible with T6963C. It supports various LCD Driver for standard or custom-made LCD module. The RA6963 built-in a 256-word CG(Character Generator) ROM that for ASCII, Japanese and numeric display in Text mode. It also supports Graphics mode and mixed display with Text. The supported maximum external display RAM is 64Kbyte and the display Window can be moved freely within the allocated memory range. The RA6963 has an 8-bit parallel data bus that can be directly connected to an 8080 series MCU. The RA6963 supports a very broad range of LCD formats by allowing selection of different combinations via a set and combination text-and-graphic modes, and includes various attribute functions. 2.
