ML9042-xx

DOT MATRIX LCD CONTROLLER DRIVER

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.
