Description

The ML9052 is an IC for dot matrix graphic LCD devices carrying out bit map display. This IC can drive a dot matrix graphic LCD panel under the control of an 8-bit microcontroller. Since all the functions necessary for driving a bit map type LCD device are incorporated in a single chip, using the ML9052 makes it possible to implement a bit map type dot matrix graphic LCD 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, is employed, it is possible to carry out displays with a high degree of freedom such as Chinese character displays, etc. With a single device, it is possible to construct a graphic display system with a maximum of 132 ¥ 97 dots. The display of ML9052 can be expanded further using two devices.

The ML9052 with a built-in RAM, which is fabricated using the CMOS process, achieves lowpower operation and is ideally suitable for displays in battery-operated portable equipment.

The ML9052 has 97 common signal outputs and 132 segment signal outputs and a single device can drive a display of up to 97 ×132 dots.

This ML9052 is not resistant to radiation or to light.
