Overview
LAPIS Semiconductor ML9059E 132-Channel LCD Driver with Built-in RAM for LCD Dot Matrix Displays FEDL9059E-01 Issue Date: April.
13, 2007 GENERAL DESCRIPTION The ML9059E is an LSI for dot matrix graphic LCD devices carrying out bit map display.
This LSI can drive a dot matrix g raphic LCD di splay panel un der t he con trol of an 8- bit microcomputer (h ereinafter des cribed MPU ).
Since all the functions necessary for driving a bit map type LCD device are incorporated in a single chip, using the ML9059E 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 ML9059E is not used in a multiple chip configuration when a line reversal drive is set.
The ML9059E 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 ML9059E 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)  Dis play RAM capacity 65  132 = 8580 bits  LCD Drive circuits 49 common outputs, 132 segment outputs  MPU interface: Can select an 8-bit parallel or serial interface  Built-in voltage multiplier circuit for the LCD drive power supply  Built-in LCD drive voltage adjustment circuit  Built-in LCD drive bias generator circuit  Can select frame reversal drive or line reversal drive by command  Bu...
