DOT MATRIX LCD CONTROLLER DRIVER
FEDL9042-01
Issue Date: Nov. 19, 2003
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
ï· Easy interfacing with an 8-bit or 4-bit microcontroller
ï· Switchable between serial and parallel interfaces
ï· Dot-matrix LCD controller driver for a 5 ï´ 8 dot font
ï· Built-in circuit allowing automatic resetting at power-on
ï· Built-in 17 common signal drivers and 100 segment signal drivers
ï· Two built-in character generator ROMs each capable of generating 240 characters (5 ï´ 8 dots)
ï The character generator ROM can be selected by bank switching (ROM1S) pin.
ï· Creation of character patterns by programming: up to 8 character patterns (5 ï´ 8 dots)
ï· Built-in RC oscillation circuit using external or internal resistors
ï· Program-selectable duties
When ABE bit is âLâ: 1/8 duty (1 line: 5 ï´ 8 dots), or 1/16 duty (2 lines: 5 ï´ 8 dots)
When ABE bit is âHâ: 1/9 duty (1 line: 5 ï´ 8 dots + arbitrator), or 1/17 duty (2 lines: 5 ï´ 8 dots + arbitrator)
ï· Cursor display
ï· Built-in bias dividing resistors to drive the LCD
ï· Bi-directional transfer of segment outputs
ï· Bi-directional transfer of common outputs
ï· 100-dot arbitrator display
ï· Line display shifting
ï· Built-in voltage multiplier circuit
ï· Gold Bump Chip
