132-Channel LCD Driver with Built-in RAM for LCD Dot Matrix Displays
GENERAL DESCRIPTION
The ML9050/9051 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. Since all the functions necessary for driving a bit map type LCD device are
incorporated in a single chip, using the ML9050/9051 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 132
￥
65 dots. The display can be expanded further using two chips.
The ML9050/9051 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 ML9050 has 65 common signal outputs and 132 segment signal outputs and one chip can
drive a display of up to 65
￥
132 dots.
The ML9051 has 49 common signal outputs and 132 segment signal outputs and one chip can
drive a display of up to 49
￥
132 dots.
This device is not resistant to radiation or to light.
FEATURES
Direct display of the RAM data using the bit map method
Display RAM data "1" ... Dot is displayed
Display RAM data "0" ... Dot is not displayed
Display RAM capacity
ML9050/9051: 65
