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.
