GENERAL DESCRIPTION

The ML9055A-02 is an LSI providing the bit map display on a dot matrix graphic LCD panel . With one chip, it is possible to construct a graphic display system with a maximum of 128 × 128 dots. Since all the functions necessary for driving the bit map type LCD panel are incorporated into a single chip, the ML9055A-02 allows to implement a dot matrix graphic LCD display system of bit map type with only a few chips in combination with an 8-bit microcomputer.

Using the CMOS process and a built-in RAM, the ML9055A-02 is highly suitable for displays in battery-operated portable equipment.
