The ML9059 is an LSI for dot matrix graphic LCD devices carrying out bit map display. This LSI can drive a dot matrix graphic LCD display panel under the control of an 8-bit microcomputer (hereinafter described MPU). Since all the functions necessary for driving a bit map type LCD device are incorporated in a single chip, using the ML9059 makes it possible to realize a bit map type dot matrix graphic LCD display system with only a few chips. Since the bit map method in which one bit of display RAM data turns ON or OFF one dot in the display panel, it is possible to carry out displays with a high degree of freedom such as Chinese character displays, etc. With one chip, it is possible to construct a graphic display system with a maximum of 49 × 132 dots. The display can be expanded further using two chips. However, the ML9059 is not used in a multiple chip configuration when a line reversal drive is set. The ML9059 is made using a CMOS process. Because it has a built-in RAM, low power consumption is one of its features, and is therefore suitable for displays in battery-operated portable equipment. The ML9059 has 49 common signal outputs and 132 segment signal outputs and one chip can drive a display of up to 49 × 132 dots.
