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.
