ML9042-xx
DOT MATRIX LCD CONTROLLER DRIVER
1/58
GENERAL DESCRIPTION
The ML9042 used in combination with an 8-bit or 4-bit microcontroller controls the operation of a character type
dot matrix LCD.
FEATURES
Easy interfacing with an 8-bit or 4-bit microcontroller
Switchable between serial and parallel interfaces
Dot-matrix LCD controller driver for a 5 × 8 dot font
Built-in circuit allowing automatic resetting at power-on
Built-in 17 common signal drivers and 100 segment signal drivers
Two built-in character generator ROMs each capable of generating 240 characters (5 × 8 dots)
The character generator ROM can be selected by bank switching (ROM1S) pin.
Creation of character patterns by programming: up to 8 character patterns (5 × 8 dots)
Built-in RC oscillation circuit using external or internal resistors
Program-selectable duties
When ABE bit is “L”: 1/8 duty (1 line: 5
× 8 dots), or 1/16 duty (2 lines: 5 × 8 dots)
When ABE bit is “H”: 1/9 duty (1 line: 5
× 8 dots + arbitrator), or 1/17 duty (2 lines: 5 × 8 dots + arbitrator)
Cursor display
Built-in bias dividing resistors to drive the LCD
Bi-directional transfer of segment outputs
Bi-directional transfer of common outputs
100-dot arbitrator display
Line display shifting
Built-in voltage multiplier circuit
Gold Bump Chip
ML9042-xx CVWA/DVWA
*xx indicates a character generator ROM code number.
*01, 11 and 21 indicate general character generator ROM code numbers.
CVWA indicates a bump chip with high hardness, and DVWA indicates a bump chip with low
hardness.
