描述 Description

GENERAL DESCRIPTION
The ML9041 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 x 7 dots) or
   32 large characters (5 x 10 dots)
• Creation of character patterns by programming: up to 8 small character patterns (5 x 8 dots) or
   up to 4 large character patterns (5 x 11 dots)
• Built–in RC oscillation circuit using external or internal resistors
• Program–selectable duties: 1/9 duty (1 line: 5 x 7 dots + cursor + arbitrator), 1/12 duty (1 line:
   5 x 10 dots + cursor + arbitrator), or 1/17 duty (2 lines: 5 x 7 dots + cursor + arbitrator)
• Built–in bias dividing resistors to drive the LCD
• Bi–directional transfer of segment outputs
