GENERAL DESCRIPTION

The ML9044A 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 8-bit or 4-bit microcontroller

? Switchable between serial and parallel interfaces

? Dot-matrix LCD controller/driver for a small (5 × 7 dots) or large (5 × 10 dots) font

? Built-in circuit allowing automatic resetting at power-on

? Built-in 17 common signal drivers and 120 segment signal drivers

? Built-in character generation ROM capable of generating 160 small characters (5 × 7 dots) or

32 large characters (5 × 10 dots)

? Creation of character patterns by programming: up to 8 small character patterns (5 × 8 dots) or

up to 4 large character patterns (5 × 11 dots)

? Built-in RC oscillation circuit using external or internal resistors

? Program-selectable duties: 1/9 duty (1 line: 5 × 7 dots + cursor + arbitrator), 1/12 duty (1 line: 5 ×

10 dots + cursor + arbitrator), or 1/17 duty (2 lines: 5 × 7 dots + cursor + arbitrator)

? Built-in bias dividing resistors to drive the LCD

? Bi-directional transfer of segment outputs

? Bi-directional transfer of common outputs

? 120-dot arbitrator display

? Line display shifting

? Built-in contrast control circuit

? Built-in voltage multiplier circuit

? Gold Bump Chip
