描述 Description

GENERAL DESCRIPTION
The ML9041A 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 100 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
• 100-dot arbitrator display
• Line display shifting
• Built-in contrast control circuit
• Built-in voltage multiplier circuit
• Gold Bump Chip
   With dummy bumps on both sides of the chip: ML9041A-xxA CVWA
   Without dummy bumps on both sides of the chip: ML9041A-xxB CVWA
