General Description

The NT7605 is a dot matrix LCD controller and driver LSI that

can operate with either a 4-bit or an 8-bit microprocessor

(MPU). NT7605 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 NT7605 also contains Character Generator RAM where

the user can store 8 different character patterns at run time.

These memory features make the character display flexible.

NT7605 also provides many display instructions to achieve

versatile LCD display functions. The NT7605 is fabricated on

a single LSI chip using the CMOS process, resulting in very

low power requirements.
