ML9058E
132-Channel LCD Driver with Built-in RAM for LCD Dot Matrix Displays
GENERAL DESCRIPTION
The ML9058E 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
ML9058E 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 65 132 dots. The display can be expanded
further using two chips. However, the ML9058E is not used in a multiple chip configuration when a line reversal
drive is set.
The ML9058E 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 ML9058E has 65 common signal outputs and 132 segment signal outputs and one chip can drive a display of
up to 65 132 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
65 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
Built-in oscillator circuit (Internal RC oscillator/external clock input)
A variety of commands
Read/write of display data, display ON/OFF, forward/reverse display, all dots ON/all dots OFF, set page
address, set display start address, etc.
Power supply voltage
Logic power supply: VDD-VSS = 3.7 V to 5.5 V
Voltage multiplier reference voltage: VIN-VSS = 3.7 V to 5.5 V
(2- to 4-time multiplier available)
LCD Drive voltage: VBI-VSS = 6.0 to 18 V
Package: Gold bump chip (Bump hardness: Low, DV)
: Gold bump chip (Bump hardness: High, CV)
This device is not resistant to radiation and light.

*8: VIN = 4.5 V, voltage multiplier capacitor C1 = 2.6 to 4.0 F, voltage multiplier output load current
I = 500 A. Only a voltage multiplier circuit operates, not activating the voltage adjustment circuit
and V/F circuit, by command “2C”.
*9: V1 load current I = 400 A. 8 V is externally input to VOUT.
The voltage adjustment circuit and V/F circuit operate by command “2B”. LCD output = no load
