Preliminary
132-Channel LCD Driver with Built-in RAM for LCD Dot Matrix Displays
1/72
GENERAL DESCRIPTION
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.
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 (during forward display)
Display RAM capacity
65
132 = 8580 bits
LCD Drive circuits

Note 5: When using an external power supply, follow the procedure for power application.
When applying external power to the V
OUT
pin only, apply V
OUT
after V
DD.
When applying external power to the V1 pin only, apply V1 after V
DD
.
When applying external power to the V1 pin to V5 pin, apply V1 to V5 after V
DD
.
Note that the above (Note 4) must be satisfied including transient state at power application.
Note 6: When using an external power supply, follow the procedure for power removal described below.
When external power is in use for the V
OUT
pin only, remove V
OUT
after V

.
When external power is in use for the V1 pin only, remove V1 after V

.
When external power is in use for the V1 pin to V5 pin, remove V1 to V5 after V

.
Note that the above (Note 4) must be satisfied including transient state at power removal.
