General Description
NT3881D General Description
The NT3881D is a dot matrix LCD controller and driver LSI that can operate with either a 4-bit or an 8-bit microprocessor (MPU). NT3881D 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 NT3881D also contains Character Generator RAM where the user can store 8 different character patterns at run time. These memory features make character display flexible. NT3881D also provides many display instructions to achieve versatile LCD display functions. The NT3881D is fabricated on a single LSI chip using the CMOS process, resulting in very low power requirements. With several NT3882 driver ICs connected to the NT3881D, up to 80 characters can be displayed.
