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). NT7603 receives control character
codes from the MPU, stores them in an internal RAM (up to
80 characters), transforms each character code into a 5 X 7,
5 X 8, or 5 X 10 dot matrix character pattern, and then
displays the codes on the LCD panel. The built-in Character
Generator ROM consists of 256 different character patterns.
The NT7603 also contains Character Generator RAM where
the user can store 8 different character patterns at run time.
These memory features make character display flexible.
NT7603 also provides many display instructions to achieve
versatile LCD display functions. The NT7603 is fabricated
on a single LSI chip using the CMOS process, resulting in
very low power requirements.
