ITO option for A-type and B-type LCD waveform General Description The NT7603 is a dot matrix LCD controller and driver LSI that can operate with either a 4-bit or an 8-bit microprocessor (MPU). The NT7603 receives control character codes from the MPU, stores them in an internal RAM (up to 80 characters) before transforming each character code into a 5 X 7, 5 X 8, or 5 X 10 dot matrix character pattern and then displaying the codes on the LCD panel. The built-in Character Generator ROM consists of 256 different character patterns. ! Character Generator ROM (CG ROM): 2 kinds of CG ROM sizes: 192 characters: 160 5 X 8 dot patterns 32 5 X 10 dot patterns 240 characters: 192 5 X 8 dot patterns 48 5 X 10 dot patterns Custom CG ROM is also available !
